( #3333=superdoc: print w/ replies, xml ) Need Help??
A friend of mine writes all his code as though the -T switch was turned on: he tests all user input, cleans the environment, so on and so forth. Then, when he thinks he's done, he runs the code under -T to see if there would have been problems.

This doesn't find all bugs in all code, but it appears to help---many subtle bugs can pop up in Perl because of incorrectly checked user input.

Personally, I prefer to cut and paste the code somewhere else, (or check it in to a branch with CVS or RCS) and rewrite what I think is incorrect. This helps me find stuff like testing for equality with `=' or `eq' where I should have used `=='.
