Really, that usage of calling setdefault without explicit default is confusing 
and useless IMHO too. I just wanted to think about possible solution if 
someone ever could think about usefulness of setdefault without default, but 
definitely in that case {float,int,object}valuemacros.h is much better and 
easier, thanks for pointing that.
