      In that state of mind you experience the wrong highlighting as a
      psygedelic effect, thus you might actually enjoy it! :-)

      Yes, I added g:filetype_pl for this.

      How often does this occur? The filetype check needs to be as good as
      possible. That includes not recognizing a Prolog file as being Perl.
      Thus we have to do some statistics based guesses.

        _This_ really only occurs if you're out for psygedelic effects,
        and vim doesn't even highlight that hash as a perl hash ;-)

                          How about "sticky filetypes" -- ie. if one is currently editing
                          a perl file, barring explicit specification such as that shown
                          above (:e myperl.pl perl), assume perl, etc.

                          Personally I'd rather an extended :e handle multiple files (:e file1
                          file2 ....); perhaps explicit filetype specification could be handled
                          via

                          :ef myperl.pl perl

                          ("edit with filetype")

                          Regards,
