Do:
perldoc -f map
and read carefully the second paragraph of discussion:
Note that $_ is an alias to the list value, so it can be used to
modify the elements of the LIST. While this is useful and
supported, it can cause bizarre results if the elements of LIST
are not variables. Using a regular "foreach" loop for this
purpose would be clearer in most cases. See also "grep" for an
array composed of those items of the original list for which the
BLOCK or EXPR evaluates to true.
Why be more obscure than you need to be?
