I did a lot of Perl, but I do not consider myself as a hacker. More of an
artist or a stylist, maybe :-). All winks apart, I try to write clear and
straightforward code, to the point of boredom sometimes, and do not like
bugs very much. In fact, I'm a child of the Dijkstra school of thought.
So I might program for years, without much chance to discover peculiarities
of a language, because I stay so safely between the tracks, all the time :-).
On the other hand, Python is so clearly designed, at least as far as I
understand it, that I'm ready to dare some unusual exploration. It's fun!

Maybe, but _this_ is rather plain. I'm not sure it would be really worth.
At least, much, much less interesting that longuest matches... :-)

I do not buy much books, but thanks for the reference, and the explanations.
You have been quite helpful to me, Tim, since I got around. Thanks a lot!
