An important point that nobody else mentioned, take a look at @a after that loop. It has been changed as well. If you wish to avoid that, then you need to copy $_ to a private variable inside of map before you manipulate it.

Oops: kyle points out that he had mentioned it. I scanned for it and thought I didn't see it. Oops. But it still bears repeating.
