[1.30 beta] Macros recursion limit detection changed #54464
I'd probably be ok with calling this a WONTFIX for now, though I'd like to think about possible ways to "future proof" things like the recursion depth better. It's worth pointing out that this particular regression won't affect consumers of the crate, right? Only its original author?
discussed at T-compiler meeting. Team is generally leaning towards closing as WONTFIX.
We did discuss various work-arounds (e.g. increasing the limit by +1 or x2... and generalizations thereof, like applying that transform also to user-provided recursion limits).
But in general no one seemed too eager to actually deploy any such "fix", and its not clear whether a better solution is available.
So, if this is still open next week in the same state with no objections, we'll close as WONTFIX.
