I see there was a long gap until two recent commits re. colours, and I'm not intimately familiar with Raku development but I know there's been active work in that time at least on the internals. So, is this mode still accurate for the version of Raku available today?
It is pretty much accurate.
Raku's syntax has been stable for years and years by now, so no additional support (except for bugfixes etc) is necessary, I would say.
