+" This is a big undertaking. Perl 6 is the sort of language that only Perl
+" can parse. But I'll do my best to get vim to.
+"
+" You can associate the extension ".pl" with the filetype "perl6" by setting
+"     autocmd BufNewFile,BufRead *.pl setf perl6
+" in your ~/.vimrc. But that will infringe on Perl 5, so you might want to
+" put a modeline near the beginning or end of your Perl 6 files instead:
+"     # vim: filetype=perl6
+
+" TODO:
+"   * Deal with s:Perl5//
+"   * m:s// is a match, not a substitution
+"   * Make these highlight as strings, not operators:
+"       <==> <=:=> <===> <=~> <« »> «>» «<»
+"   * Allow more keywords to match as function calls(leave() is export(), etc)
+"   * Optimization: use nextgroup instead of lookaround (:help syn-nextgroup)
+"   * Fix s''' substitutions being matched as package names
+"   * Match s/// and m/// better, so things like "$s/" won't match
+"   * Add more support for folding (:help syn-fold)
+"   * Add more syntax syncing hooks (:help syn-sync)
+"   * Q//:
+"       :to, :heredoc
+"       interpolate \q:s{$scalar} (though the spec isn't very clear on it)
+"
+" Impossible TODO?:
+"   * Unspace
+"   * Unicode bracketing characters for quoting (there are so many)
+"   * Various tricks depending on context. I.e. we can't know when Perl
+"     expects «*» to be a string or a hyperoperator. The latter is presumably
+"     more common, so that's what we assume.
+"   * Selective highlighting of Pod formatting codes with the :allow option
+"   * Arbitrary number, order, and negation of adverbs to Q//, q//, qq//.
+"     Currently only the first adverb is considered significant. Anything
+"     more would require an exponential amount of regexes, making this
+"     already slow syntax file even slower.
+"
+" If you want to have Pir code inside Q:PIR// strings highlighted, do:
+"  let perl6_embedded_pir=1
+"
+" The above requires pir.vim, which you can find in Parrot's repository:
+" https://svn.parrot.org/parrot/trunk/editor/
+"
+" Some less than crucial things have been made optional to speed things up.
+" Look at the comments near the if/else branches in this file to see exactly
+" which features are affected. "perl6_extended_all" enables everything.
+"
+" The defaults are:
+"
+"  unlet perl6_extended_comments
+"  unlet perl6_extended_q
+"  unlet perl6_extended_all
+
+" quit when a syntax file was already loaded
+if exists("b:current_syntax")
+    finish
