[Scala] "with" keywords highlighted as out of place when comment between them and extends

[fhunstock-semron]

What happened?

Given the following scala code,
this will highlight the with keywords as out of place:

class c()
    extends a()
    // some comment
    with foo with bar {

    }

while the following works fine:

class c()
    extends a()
    with foo with bar {

    }

Tested on build 4143 on the stable channel

This may not actually be solvable.

The problem here is inferring when the class definition ends in general (especially when you don't have an open curly brace) is based on a complex series of rules, most notably including a double newline. This is the same set of rules that applies to other type definitions. The issue in your example is there is a double newline, it's just hidden by the comment. Scala reasonably considers the comment line to be "not blank", but it's harder for Sublime to make the same judgement.

I would definitely like to fix this, but I'm somewhat skeptical that it's in the cards.
