Yes thanks, I read that shortly after you wrote it, and decided to try to implement
something.  I cut some corners by using tcc to generate the plugin dll, so 
I should be able to port the idea easily enough from Windows -> Linux without
understanding ELF/PE formats.

I'm glad you suggested this.  I looked into decorators but all I found 
was PEPs, so assumed they weren't already implemented in 2.4!

Now found the docs at:  http://www.python.org/doc/2.4/whatsnew/node6.html
I'll do it like that once I get my head round decorators.
