Well... Sometimes it's just the walk, sometimes somebody asks me to do something (then it's not mine), but in most cases it's reengineering - i like to have things done my way :-)
I know that my way is the ugly one (many people did the same thing other - better way), but i like it as long as it fits my needs. Last time i needed to read several different (and growing) files... None of CPAN modules did what i wanted... One was slow as a snail, second only told me which files i'm able to read from, etc... so i wrote my simple (IMHO) code, which isn't so kind as those modules from CPAN, but it's ok - it works, even with strict!

I've just realized, that my "dream" is an OS written only with Perl ;-) but by that time i follow the KISS rule. Keep it simple, stupid ;-) so i automate more and more things... And just between, there is something i can call "an inspiration" :-)

Good luck!
