This is probably the way to go, though it's probably worth looking at
what comes out of the current python-dev discussion of adding enums to
the standard library.

I do think pickling and copying should work out of the box.  The code to
handle enums is generated by shiboken so changing the code generator
will affect all (or at least nearly all) of the places enums are used.
I'm also relatively unconcerned about the overhead since the other steps
in the value conversion process probably will take more time than
finding the correct value.  We do need to be concerned about backward
compatibility and source compatibility with PyQt.
