Fix ICE when passing block to while-loop condition We were incorrectly delaying a bug when we passed _any_ block (that evaluated to `()`) to a while loop. This PR makes the check a bit more sophisticated. We should only suppress the error here in cases that are equivalent to those we find in #93574 (i.e. only while loop conditions that have destructuring assignment expressions in them). Fixes #93997 cc `@estebank` who added this code I would not be opposed to removing the delay-bug altogether, and just emitting this error always. I much prefer duplicate errors over no errors. |
