That's the colon in isfname (which I do have), rather than the one in
iskeyword (which I don't, but perhaps I should).

Indeed (though there's an irritating bug where if I have something like
~/lib/perl/ early in my path and CGI::Lite is installed there then when
Perl searches for CGI will find the _directory_ ~/lib/perl/CGI/
(necessary for CGI::Lite), rather than (which is later in the
path).  There's some magic which says "also check for this filename with
'.pm' on the end", but we really want that to be "only" rather than

The last time I looked at that I couldn't see a way of fixing it.

I have this in ~/.vim/after/ftplugin/perl.vim:

  let &l:path = system('perl -I, -Ilib -I../lib -e "print join q[,], @INC"')

That adds in ./lib/ and ../lib/.  But it'd be good to look for use lib
statements and similar in the code and add those in too.

May God bless us with enough foolishness to believe that we can make a
difference in this world, so that we can do what others claim cannot be done.
