Of course it is something that BSD can execute. You just don't happen to
have an executable called perl^M in /usr/bin/. :)

Anyway, since most systems don't have it either, I almost always put -w
on the #! line even if my script is bound to run on 5.8, which supports
the warnings pragma, to exploit the behavior you encountered here. Looks
like I wasn't the only one.
