Could you rebase on top of main? There have been a few changes to lambda that i think address part of the issues here, but this patch is still very much needed.

We add a bug when referring to a capture in a decltype or a require would cause a crash, and that is fixed. I suspect the salient part of your patch is the addition of the parameters of the enclosing function.
