Yeap, I agree with the original point too (as I explained in the rest of 
my comment)... just didn't think it was a 'fair' comparisson. ;-)
-- me? When I use java I write 1.5 code and 'retroweave' it to be 
compatible with java 1.4 (Pydev is done this way) -- and I use Python at 
work -- and I'm very happy with it... I just think that a language is as 
a tool, and each may be suited better for a different occasion.

The 'usually smaller' I mentioned is because sometimes java code gets 
smaller because of the already-existing codebase... E.g.: for developing 
an IDE, Eclipse already has a huge codebase, so, if I wanted to do all 
that was already done in it in python just because Eclipse was in java, 
I think I would be doing the wrong decision, and besides, I could use 
jython for it if I wanted to...

And from what I understood, the original poster had a large codebase in 
java already, so, I'm not sure that changing  everything to python would 
be the way to go (altough that DOES depend a lot on the original 
codebase quality).

Cheers,

Fabio
