Hmm, I think that the usage of @constructor has become somewhat conflated with @type as in many highlight queries it applies to all identifiers with ^[A-Z]. I'm fine with this change.

The recent commits we made to this PR fixed up the usage of @constructor so it is no longer conflated with @type in python at least. I suspect originally that was the main motivation for @Zeddicus414 wanting to change this. For style reasons, maybe the change here is still a good idea. I just thought I'd point this out.
