Description

Problem*

Relates to #1344 (comment) but does not solve the issue.

Summary*

Slices cannot be supported for println yet as we do support slices as an entry point for Brillig generation. This is because the Brillig entry point expects a set amount of expressions and it cannot be unknown. Slices will not be supported in Brillig gen until we add another pass or some other context information to track slice sizes. Once slices are enabled for Brillig entry points the linked issue will be able to be fully resolved.

For now, this PR simply clarifies the error so that the user does not get information about the main func and the ABI:

Message:  internal error: entered unreachable code: println does not support slices. Convert the slice to an array before passing it to println
Location: crates/noirc_frontend/src/monomorphization/mod.rs:761

This is a bug. We may have already fixed this in newer versions of Nargo so try searching for similar issues at https://github.com/noir-lang/noir/issues/.
