I think that there's a close correlation between Environment in SCons and 
property-set. Environment holds values of "construction variables". 
property-set holds values of features. At a later stage, V2 converts values 
of features into values of variables which are used in build action. It looks 
like converting property-set to Environment is reasonable approach.

OTOH, I can't comment if Environment is better for us that plain Python 
map ;-)
