Actual behavior

Neither of them are highlighted:

dyn support should be added in #308.

AFAIK, specialization is not yet stable, correct? I've been reluctant to add support for unstable features.

[sampersand]

Specialization isn't stable currently :(; does that mean nightly features won't be added in?

does that mean nightly features won't be added in?

I don't have a strong opinion about it. There is a backlog of stable syntax to fix, so that will probably get priority.

[sampersand]

true, but default is context-specific; you'd just add it in right before impl, and that'd be it
