Syntactically, "for" can always be swappped with "foreach". However, there are definitely two different styles of loops. Traditionally, the "for" loop is the "C-style for loop", with an initializer, test, and iterator expression trio. And "foreach" loop is the "csh-style foreach loop", with a single scalar being walked through a list of values. But in Perl, you can spell either of these loops "for" or "foreach". Most Perl hackers tend to optimize for the shorter word when possible, although in Learning Perl, we were careful to always use the "proper" word. print "Just another Perl (book) hacker," -- Randal L.
