I'm not sure that Python is closer to C++ than Ruby is, especially not

I don't know that os.path.walk is slow. What exactly are you doing in each
directory? Maybe the way you are searching for file extensions is inefficient,
for example. Please post some example code.
Of course, it's also possible that Ruby is intrinsically faster than Python
here, but let's not assume that for now. :-)
