The Blue Camel has this to say about map on page 741:

Because $_ is an alias (implicit reference) into the list's values, this variable can be used to modify the elements of the array.

So you'll be modifying the orginal value, weather it was a list of references or not. Mearly chomping the value, as the code posted does, is unlikely to do real harm, so I wouldn't consider it a problem in this case.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
