Yeah, that's going to be fun when the 'push incompatible changes'
mentality reaches the Python interpreter. Oh, wait - when it affects
RHEL's own work, they hold back...

You get programming efficiency with well designed high level library
component support with stable interfaces regardless of the language
itself.  How long would it take you to hook a perl or java program to
a new sql database (assuming you aren't the first one to ever do it)?
Or parse some xml?   The things that kill programmer time are when you
have to do tedious tasks like that from scratch or deal with interface
changes in the code that was supposed to handle it.
