I would agree. `foreach` always aliases the iterator to the list items, rather than copying. That means when you use a predeclared variable, its old value will be shadowed during the loop and restored afterwards. I have never had any use for this behaviour (other than for the fact that this makes `foreach` the safest way to make use of `$_`) and I strongly doubt it is something we want novices to be concerned with. And the clutter it might add to the examples is so minimal as to be of no concern. Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>Thread Previous | Thread Next
