This is can be problematic when you have advanced introspection. 
This could potentially ruin future language advances (more 
powerful introspection).

I don't think the community should assume that what works for 
other languages will serve D well.

Basically, maintaining multiple versions of a standard lib for a 
language that is evolving is overreaching. You get another layer 
of issues in addition to the ones you already have.
