What about adding this to object.di:
class Hashable : Object {
int opCmp(Hashable h) @safe const { ... }
bool opEquals(Hashable h) @safe const { ... }
hash_t toHash() @safe const { ... }
}
Whatever objects need to be put in AAs can just inherit from Hashable.
Or will this introduce more problems than it solves?
