As already said my is much younger than foreach and it's consistent and backward compatible.
While looping over localized globals could also be done with an extra local $packvar=$lex_for_var, the aliasing effect of foreach can't be achieved in any other way in core Perl.
For a detailed discussion, see How do closures and variable scope (my,our,local) interact in perl?.
UPDATE: expanded code, fixed typos
