I liked a few of the replies a lot (++s around) and I'd never dispute the wisdom of leaving it to the coder. But I think something like this could be useful to others besides toma.

I was trying to read some procedural Perl about a year ago that was written by a C coder making a dip into Perl for the expediency. It was almost 1_000 lines long and didn't contain more than one or two variables that were longer than one letter. There isn't enough espresso in Abyssinia to keep my focus that strong.

This could be useful for keeping certain minimum style requirements in a tech group.
