I tried to fix a bug in Signal a few years ago. One part of the code took so long to do type inference on my poor old Intel MacBook that the Swift compiler errored out. I suppose waiting was out of the question, and I needed a faster computer to be able to compile the program. That was pretty horrifying. I’ve never seen a compiler that errors nondeterministically based on how fast your cpu is. Whatever design choices in the compiler team led to that moment were terrible.
