Martian allows you to use a similar spelling to metaclasses (base 
classes), without the weird surprises during run-time (after 
configuration is already done), and without significant import-time 
side-effects.

With megrok.rdb I actually use SQLAlchemy declarative without their 
declarative metaclass, as the SQLAlchemy folks were kind enough to tweak 
their config code so I could call it directly from a grokker.
