In Python there's are some common utility functions in python/handle.c
and python/utils.c.  The generated code can call those functions.

As for other repeated code I wouldn't worry about it too much.
Another point of the generator is to automate boilerplate, to behave
like an exceptionally precise programmer.  If there's a bug in the
boilerplate there's only one place we have to change.
