I think it is possible. You can fool python's idea of what a module is quite
In : sys.modules['code'] = sys.modules['time']
In : code.<TAB>
code.accept2dyear code.daylight code.strftime code.tzname
code.altzone code.gmtime code.strptime code.tzset
code.asctime code.localtime code.struct_time
code.clock code.mktime code.time
code.ctime code.sleep code.timezone
These are all time's functions :)
In : reload code
Out: <module 'time' from '/usr/lib/python2.3/lib-dynload/timemodule.so'>
So I think what you have in mind should work. My only concern is that you
seem to want to reload the _original_ wx/__init__.py, so I'm not sure I
understand correclty where you want to do the trapping. But overall, I think
this kind of game can _definitely_ be played from the outside of Wx. This is
one of the benefits of python's extremely strong dynamic nature.
