I understand that, and empathize with how much you’ve got on your plate. It’s just a little disappointing to be told, “macros can do this”, but have no way to proceed other than forking the compiler and implementing the macro there first - and yes, that was a real suggestion.
An example of this was the back-and-forth in the thread on Curried Varargs, which started at the very end of November and involved over a week of burning my evenings failing to figure out something that @nicolasstucki was able to produce in a couple of hours (and I cannot stress enough how much I appreciate him doing that).
I’d hazard a guess that, if each time someone close to the implementation was tempted to comment something along the lines of, “have you tried a macro for this?”, that if they provided a concrete example of how one could go about doing this using a macro or other metaprograming techniques, then it would come up less often as the body of examples grows.
If they don’t have time to provide some actionable hint, and I totally understand that may be the case as everyone’s time is both limited and generally overbooked, maybe “have you tried a macro for this?” isn’t actually helpful, and it might be worth considering not commenting it.
