std crate not found: https://godbolt.org/z/FyuZHY
Could be multiple/old versions of rust lying around: https://stackoverflow.com/questions/24417183/cant-find-crate-for-std-compiler-error-with-trivial-code
This is still broken!
Nightly compiler is working for me as of right now.
You're right, it's working again! I think this can be closed?
