Let analyzer detect out of scope references in all comments

[bergwerf]

I often use [reference] in my comments to refer to fields or variables. Sometimes when I refactor the analyzer helps to remind me that I have to update some comments. Unfortunately this does not work for non-documentation comments (i.e. //).

this is something I do too. It would be nice if all comments were treated as documentation comments for this purpose, as sometimes even if it will not result in documentation, having the links for code navigation in IDEs is nice.
