I must confess, I voted for improperly formatting my code. I
only indent my blocks 1 space, which some people find slightly annoying. I don't like tabs, or using vi's autoindent, so its probably a result of being lazy and saving wear and tear on my thumb. At least I indent consistently, lining up all the lines in a block with closing braces in sub blocks, which is more than I can say for a lot of the code I've seen :)
And I've always been meaning to write a perl program to change the indentation to any desired number of spaces...(No, not a prettyprinter - I'm not THAT ambitious).
Update: My gosh, this node is old. I have heard of perltidy since I first wrote this, and I've since mended my one-space indentation ways. I'm up to two spaces now :-)
