Add Perl 6 syntax highlighting on exercism.io

[m-dango]

Currently, there is no highlighting for Perl 6 code on exercism.io. It appears that exercism.io is using Rouge:
https://github.com/exercism/exercism.io/blob/master/lib/exercism/syntax_highlighter.rb

Perhaps it would be possible to port from pygments to Rouge?

There's an existing issue to add support for Perl 6 in rouge-ruby/rouge#390

Is highlighting at the exercism/exercism.io repository level?

[kytrinyx]

If the track ID doesn't match the language name in jneen/rouge, then we need to add it to the map of ids to rouge names: https://github.com/exercism/exercism.io/blob/master/lib/exercism/syntax_highlighter.rb#L6-L16

Raku syntax highlighting appears sometimes off.

Strangely not in the web editor but in published solutions.

For an example, look at lines 4-5 of this Luhn solution. It appears the regex containing <digit> throws things out of kilter.

@habere-et-dispertire can you open a new issue? This one is for "no highlighting" as opposed to broken highlighting.

There is a related issue upstream rouge-ruby/rouge#390

New Issue #520 .

Nice, thanks for the breadcrumbs.
