How to rescan for mode comment in new buffer?

[KARR, DAVID (ATTCINW)]

If I've created a new empty file and pasted in the header that will make
the shell and Emacs recognize it as a Perl script, what's the easiest
way to "refresh" it so that Emacs recognizes that it has to go into Perl
mode?  I could just manually run "perl-mode", but I'd rather a cleaner
way to do it.  Saving, killing the buffer and reloading it seems
excessive also.

M-x normal-mode RET

saving and executing M-x revert-buffer will do the trick.

or set up auto-mode-alist so that it recognises the major mode from the
extension that you give your perl scripts (if you give them a fixed extension,
that is.)
