I am afraid to look into the aby... at obfuscated/golf code, since I am afraid it might look ba... be contagious.

(-: Are you saying that I should relax -- it helps keyboard speed if my fingers transform into tentacles and Cthulhu worshippers can scuba dive cheaper because of breathing under water? :-)

I recently learned how neat parsing parameters is with Getopt::Long.

What I've learnt the last year or so is to write tests for all code I write. The main advantages are development speed (for larger code), that you organize your code differently so it is testable and it really helps when you rewrite code.

For my hobby project, I'm going to make an alternative implementation of a feature (big data volumes will be stored in a sql database). I can copy the tests and keep the interface! Neat.

Since that was borderline elegant, I'll also show a monk's humility by mentioning a horrible kludge I'll add to that. Objects will rebless themselves to the other implementation type when the data size gets larger/smaller! (A nicer implementation would be to have an implementation of the storage which are contained in another object -- and let that create/delete objects with data. That gets complicated for other reasons.)

[stevieb]: it's a long day when you want to make changes to a project and the entire test suite takes 2 hours to fully run :)
choroba knows the situation. At work, unit tests run for 30 minutes, and integration and end-to-end tests take almost one hour.
