I guess I’ll just add my motivation – I’ve had to debug multiple race conditions in SymbolicRegression.jl which nowadays is quite a complex library with deep call stacks, a lot of memory optimizations, asynchronous stuff, buffers, etc. Every race condition\[1\] is an absolute pain to debug. In retrospect it feels like each one could have been prevented with a borrow checker.

At the very least it would be nice if there was some sort of pure-Julia MemCheck/Sanitizer that could find such things automatically. (But maybe I’m just not fluent enough in parsing Valgrind analysis into the Julia side)

1. I mean race conditions produced within SymbolicRegression.jl; I haven’t had one in Base yet, luckily, other than some GC issues I found in 1.11.
