The Perl documentation states, in perlsyn, that they are exactly the same thing. In Perl, there are many ways to do things. Perhaps it makes more sense to you to use 'foreach' when iterating over an array, and 'for' when doing a C-style loop. Personally, I always use 'for' because that's why I prefer. tr/// and y/// are the exact same thing.
