Only if there are no ordering constraints and no need for multiple 
elements with the same name.  The make statement was built to mirror the 
the class statement, so the body is just executed in a regular Python 
dict.  Hence, you can only have one value for each name, and the order 
in which the names appear is not maintained.  There's some discussion of 
workarounds_ for this in the PEP, but they're pretty hackish.
