While working on some issue, I was searching for existing tests for string which landed me at OperatorsModule2.fs. However, searching for the actual test [<Test>] test.string() inside the Test Window turned up nothing.

I also noticed that the coloring was way off, and type inference did nothing. For instance notice the "unused var" color on result:

After some 🤯 it dawned to me and I found this:

In other words, it is marked as Content. Is this deliberate? It is also true for some, but not all, other files in FSharp.Core.UnitTests, which suggests that the tests are not run. Can I change it so that it actually compiles, or should I only ever do that local-only?

EDIT: it probably is deliberate, as there's a bunch of code there that doesn't compile when I enable it. I wanted to work on #7958 and possibly this #9153, but that would mean re-enabling these tests, or putting them elsewhere.

@vzarytovskii, I believe you are working on restructuring the tests, what's the best cause of action here?
