And alter syntax highlighting: it has a few `\k` atoms (perlFormat,
perlFormatName) and lots of `\<`/`\>` tokens. On a real world file
(one of my old projects) this does not change too much (mostly
highlighting of things like Module::open: open function with explicit
module), but I cannot say how significant changes will be for other
projects.
