It can be very hard to debug (from a compiler engineers perspective) why the perforamnce diagnostics aren't allowing a certain pattern. Usually this means adding a bunch of random SIL dumps to debug. With these stack traces, you can now just add
-Xllvm -swift-diagnostics-assert-on-error=1
and the stack dumps will do the rest.
