Proposed filetype detection for Perl/Pod 6

[Hinrik Örn Sigurðsson]

Currently, to make sure that vim associates the 'perl6' filetype with
your Perl 6 code, you have to put a "vim: filetype=perl6" modeline
near the beginning/end of your source file. This is suboptimal,
however, because when vim processes the modeline, it has *already*
sourced the ftplugin/syntax/indent files for Perl 5. Aside from
performance reasons, this poses a problem for Perl 6's ftplugin file
because where they differ, the Perl 6 one must undo some changes made
by the Perl 5 one.

So, to do this properly, we have to patch vim's filetype.vim and
scripts.vim, which handle filetype detection. I have made the
following patches, and they work very well at detecting Perl/Pod 6.

filetype.vim.diff: http://gist.github.com/179863
scripts.vim.diff: http://gist.github.com/179865

If you don't want to apply the patches or wait for vim to include
them, the same can be accomplished by putting the code into
~/.vim/filetype.vim and ~/.vim/scripts.vim on your machine.

So the key is, we're looking for suggestions on how to do it better.
I also fear that the "use v6/whatever" will not be robust enough.

As far as I know, this logic is what has been proposed for the Perl 6
specification. That is, all Perl files will be considered to be Perl 5
unless the first like of code is "use v6" or a
grammar/class/module/role declaration.
