( #3333=superdoc: print w/ replies, xml ) Need Help??

When using strict perl requires to declare even the loop variable of a foreach loop.

It can use package variables, for starters.

our $foo; sub f { print("$foo\n"); } for $foo (qw( a b c )) { f(); # Prints a, b and c. }

Foreach loops existed long before "my".

Why is this code not allowed?

It generates an error for all instances of $word since you never declared it and you asked to make such things errors.
