Greg was being a but jocular here. I didn't take him seriously. But 
there's maybe a better case to make the point he was making. Back in the 
dark ages we used a source code control system called CVS. It's quite 
unlike git and has a great many limitations and uglinesses, and there 
was some pressure for us to move off it. If we had done so when it was 
first suggested, we would probably have moved to using Subversion, which 
is rather like CVS with many of the warts knocked off. Before long, some 
distributed systems like Mercurial and git came along, and we, like most 
of the world, chose git. Thus by waiting and not immediately doing what 
was suggested we got a better solution. Moving twice would have been ... 
painful.

I have written Python in the past. Not a huge amount, but it doesn't 
feel like a foreign country to me, just the next town over instead of my 
immediate neighbourhood. We even have a python script in the buildfarm 
server code (not written by me). I'm sure if we started writing tests in 
Python I would adjust. But I think we need to know what the advantages 
are, beyond simple language preference. And to get to an equivalent 
place for Python that we are at with perl will involve some work.


cheers
