RE: [Jython-users] Madness in the method ??

[Alan L. <al...@li...>]

Ype,
      I know rebinding the functions works as you showed -- my actual
problem is slightly trickier because I need to apply some renaming
algorithms in a rather wholesale way to the method names in a very dynamic
fashion (based on how they are being called elsewhere) -- hence it seemed
that __getattr__ was the right place to do this kind of monkey business
(which, by the way, P/Jython is _very_ good at).

I guess I am still in the dark a little as to why my approach didn't work
(the docs didn't seem to shed too much light on this dark corner) -- when I
can free up some time I'll check out the sources and figure out my
misunderstanding.

Tnx
Alanl
