package p

type U struct{}
func (U) f()
Use the object's package to mangle method names, rather than the receiver's package If we use the receiver's package, we can end up with identical manglings for different functions. Consider: package p type U struct{} func (U) f() package q import "p" type T struct { p.U } func (T) f() The method set of T has two synthetic methods named (T).f(); one forwards to (T).f(), and the other to (U).f(). Previously, we were distinguishing them by the receiver's package, and in this case because both methods have the same receiver, they received the same name. The methods are correctly distinguished by the package owning the identifier "f", which is available via f.Object().Pkg().
