I suppose you mean using "dict" as a variable name, and f2py using
types.DictType which is "dict" in Py3? 2to3 does not handle those.
Using builtin names as variable names is bad practice, so when I met
that in SVN, I just changed the variable names to something more sane.

The best alternative, imho, is not to use "dict" as a variable name at
all. We should make that change manually in SVN sources, both for Py2
Grepping the f2py source shows that this problem occurs only in
auxfunc.replace, so changing that shouldn't be too much work.
