in reply to Favorite Descriptive Variable Name
I really like $foo when discussing code theoretically, but I never use it for actual programming. I frequently throw in $myInt's or such for quick things. In most other languages, I will usually label arrays as such, i.e.
var clientArray = new Array();but this is of course redundant in Perl, which is nice because adding "Array" onto the end of a half dozen variables eventually takes up a lot of valuable horizontal space.
