Thank you all for you great tips! Matteo's list comprehension solution
suits best my particular problem and I'll be using it.

It was great to know about the Numeric package, Peter, it will be really
useful for some of the matrix handling I'm going to need.
Anton's solution was a good brain teaser. I couldn't find in the docs what
is the meaning of the asterisk in zip(*d), though. Nothing to do with C
pointers, I guess?
