Now that generics is coming along, is there an easy way to extend the
builtin map type to use a non-comparable key type? For example, given this
constraint
type Key[T any] interface {
Size() uint64
Hash(seed uint64) uint64
Equal(T) bool
}
and a type Foo like
type Foo []int
func (a Foo) Size() uint64 { ... }
func (a Foo) Hash(seed uint64) uint64 { ... }
func (a Foo) Equal(b Foo) bool { ... }
I'd like a map[Foo]struct{}. Is this possible now? Or does the runtime map
have to be updated to support this?
