[Grace-core] Dialect encoding

The anonymous enclosing scope probably isn't necessary with magic. With
my encoding you have to create a new object and perform the inheritance
operation on it, with magic you can just stick things into the current
scope directly.

In this case, just how the method lookup occurs: who has access to what,
really.
