Thanks for reporting @JosephTLyons!

I was able to produce an error outside the repl as well:

❯ roc build hello.roc 
An internal compiler expectation was broken.
This is definitely a compiler bug.
Please file an issue here: <https://github.com/roc-lang/roc/issues/new/choose>
ambient functions don't unify

❯ cat hello.roc 
app [main!] { cli: platform "https://github.com/roc-lang/basic-cli/releases/download/0.19.0/Hj-J_zxz7V9YurCSTFcFdu6cQJie4guzsPMUi5kBYUk.tar.br" }

import cli.Stdout

main! = |_args|
     Stdout.line!(Inspect.to_str(Num.pow(4,2)))

I believe the repl also uses Inspect.to_str so that may be the source of the problem.

I thought this issue only appeared recently but it's even present in commit 0d9db5b from the 9th of July, I did not check older commits.
