At least the ones about `this` capture seem to be working and covered. Not all of them have the same behavior as described though, for example on https://eel.is/c++draft/expr.prim.lambda#closure-6 clang complains about missing capture, though gcc agrees https://godbolt.org/z/hfxbEP5fW , so this is probably a bug in the example. Anyway I think this is a bit out of the scope of the patch.
