// Package objectpath defines a naming scheme for types.Objects
// (that is, named entities in Go programs) relative to their enclosing
// package.
//
// Type-checker objects are canonical, so they are usually identified by
// their address in memory (a pointer), but a pointer has meaning only
// within one address space. By contrast, objectpath names allow the
// identity of an object to be sent from one program to another,
// establishing a correspondence between types.Object variables that are
// distinct but logically equivalent.
//
// A single object may have multiple paths. In this example,
//
// type A struct{ X int }
// type B A
//
// the field X has two paths due to its membership of both A and B.
// The For(obj) function always returns one of these paths, arbitrarily
// but consistently.

// sequence of destructuring operations applied to the package scope
// to obtain the original object.
// The name does not include the package itself.
type Path string
// Encoding
//
// An object path is a textual and (with training) human-readable encoding
// of a sequence of destructuring operators, starting from a types.Package.
// The sequences represent a path through the package/object/type graph.
// We classify these operators by their type:
//
// PO package->object Package.Scope.Lookup
// OT object->type Object.Type
// TT type->type Type.{Elem,Key,Params,Results,Underlying} [EKPRU]
// TO type->object Type.{At,Field,Method,Obj} [AFMO]
//
// All valid paths start with a package and end at an object
// and thus may be defined by the regular language:
//
// objectpath = PO (OT TT* TO)*
//
// The concrete encoding follows directly:
// - The only PO operator is Package.Scope.Lookup, which requires an identifier.
// - The only OT operator is Object.Type,
// which we encode as '.' because dot cannot appear in an identifier.
// - The TT operators are encoded as [EKPRUTC];
// one of these (TypeParam) requires an integer operand,
// which is encoded as a string of decimal digits.
// - The TO operators are encoded as [AFMO];
// three of these (At,Field,Method) require an integer operand,
// which is encoded as a string of decimal digits.
// These indices are stable across different representations
// of the same package, even source and export data.
// The indices used are implementation specific and may not correspond to
// the argument to the go/types function.
//
// In the example below,
//
// package p
//
// type T interface {
// f() (a string, b struct{ X int })
// }
//
// field X has the path "T.UM0.RA1.F0",
// representing the following sequence of operations:
//
// p.Lookup("T") T
// .Type().Underlying().Method(0). f
// .Type().Results().At(1) b
// .Type().Field(0) X
//
// The encoding is not maximally compact---every R or P is
// followed by an A, for example---but this simplifies the
// encoder and decoder.

// Concrete methods can only be declared on package-scoped named types. For
// that reason we can skip the expensive walk over the package scope: the
// path will always be package -> named type -> method. We can trivially get
// the type name from the receiver, and only have to look over the type's
// methods to find the method index.
//
// Methods on generic types require special consideration, however. Consider
// the following package:
//
// L1: type S[T any] struct{}
// L2: func (recv S[A]) Foo() { recv.Bar() }
// L3: func (recv S[B]) Bar() { }
// L4: type Alias = S[int]
// L5: func _[T any]() { var s S[int]; s.Foo() }
//
// The receivers of methods on generic types are instantiations. L2 and L3
// instantiate S with the type-parameters A and B, which are scoped to the
// respective methods. L4 and L5 each instantiate S with int. Each of these
// instantiations has its own method set, full of methods (and thus objects)
// with receivers whose types are the respective instantiations. In other
// words, we have
//
// S[A].Foo, S[A].Bar
// S[B].Foo, S[B].Bar
// S[int].Foo, S[int].Bar
//
// We may thus be trying to produce object paths for any of these objects.
//
// S[A].Foo and S[B].Bar are the origin methods, and their paths are S.Foo
// and S.Bar, which are the paths that this function naturally produces.
//
// S[A].Bar, S[B].Foo, and both methods on S[int] are instantiations that
// don't correspond to the origin methods. For S[int], this is significant.
// The most precise object path for S[int].Foo, for example, is Alias.Foo,
// not S.Foo. Our function, however, would produce S.Foo, which would
// resolve to a different object.
//
// For S[A].Bar and S[B].Foo it could be argued that S.Bar and S.Foo are
// still the correct paths, since only the origin methods have meaningful
// paths. But this is likely only true for trivial cases and has edge cases.
// Since this function is only an optimization, we err on the side of giving
// up, deferring to the slower but definitely correct algorithm. Most users
// of objectpath will only be giving us origin methods, anyway, as referring
// to instantiated methods is usually not useful.
