Wow, I didn't know that, and I have been using Perl for some time. Never
too old to learn.

The answer is in 'perldoc perlsyn':
The "foreach" loop iterates over a normal list value and sets the
vari-
able VAR to be each element of the list in turn. If the variable is
preceded with the keyword "my", then it is lexically scoped, and is
therefore visible only within the loop. Otherwise, the variable is
implicitly local to the loop and regains its former value upon
exiting
the loop. If the variable was previously declared with "my", it
uses
that variable instead of the global one, but it's still localized to
the loop.
The last sentence is important here: Even though $t is a lexical
variable in your program, it's value is nonetheless localized inside
the
loop and regains its previous value when leaving it.
