Are those the only two options? See wikipedia for a longer list of styles. I use banner style, and I also have my reasons to use it: I thought about it. I'm afraid a lot of fresh coders just follow what they were fed at school or what their editor-of-choice gives as prefered style.
sub foo
{
if (bar) {
# Blah!
}
} # foo
WAY more important than what style is used, is that the style is used consistently and by all members in the team.
FWIW I do not think this would be a good poll. It would lead to flame wars.
Enjoy, Have FUN! H.Merijn
