Yes it could, but it would hurt performance (I should profile more 
thoroughly, but I think we are talking about several times slower).

I will try to expose some simple cases in a later email about some 
problems.  A. M Archibald already gave some answers, though.

It is even easier than that, since I already have a svn account (I am 
the maintainer of the package pyem, for Gaussian Mixture Models). Is 
there a name I should pick, or can I just create a directory with my 
name like rkern or oliphant and start hacking there ?
