IO.warn doesn't stop compiler with --warning-as-errors

In my project, I have a compile-time code that can generate some warning depending on some circumstances.

To show the warning I do IO.warn(“…”).

The problem is that, with this, the compiler will happily continue even if I add –warning-as-errors option.

Shouldn’t that option make the compiler fail in this case or am I missing something here?

In this example, you have used --warning-as-errors and not --warnings-as-errors

FWIW, IO.warn/1 directly calls IO.warn/2:

@sezaru - long shot, but is it possible you’re running into something weird from the tail-call optimization mentioned in the docs for IO.warn/1?
