@eric-wieser eric-wieser commented Feb 9, 2024

There was a bug in the tactic that meant it would always print "no goals to be solved".

This also promotes the code-generation from IO to CoreM, so that the output can be sent through the logging infrastructure rather than IO.println.
This is important, because tests are not allowed to be noisy, and we have no way to capture IO output.

There was a bug in the tactic that meant it would always print "no goals to be solved".

This also promotes the code-generation from `IO` to `CoreM`, so that the output can be sent through the logging infrastructure rather than `IO.println`.

The wording could probably be improved here, but I'd prefer to declare that out of scope; this PR is blocking a bug fix elsewhere, as we cannot write tests without it.
