Yes we are, I just want to see them exposed :)

The classiness of maps is also a type definition.  If you define class as a set of known behaviors map as class works. 

Exposing the underlying map implementation tothe language layer could provide an interesting way to guard or hook method sends. 

Think assert x is a foo, therefore x can bar, but x doesn't bar so x is not a foo. You can walk the mirror and extract this data, but you loose the history of transformation.

As always you are a font of information, thanks Jecel.
