Description

Problem*

Resolves #4436

Summary*

This issue stemmed from calling another trait method within an impl for the trait. The trait method required a trait constraint of the same trait to be valid and was using the trait with its original type variables. These would later be bound over when an impl was searched for for this trait.

I've added a somewhat hacky solution of avoiding inserting t = t bindings from the trait constraint when checking identifiers. Avoiding inserting this binding means t in this case will later be instantiated to a fresh type variable later on in the instantiate_with_bindings call.

Additional Context

Documentation*

Check one:

  • No documentation needed.
  • Documentation included in this PR.
  • [Exceptional Case] Documentation to be submitted in a separate PR.

PR Checklist*

  • I have tested the changes locally.
  • I have formatted the changes with Prettier and/or cargo fmt on default settings.

I pushed 4cb9cce to remove Nargo.toml from the gitignore. I'm not sure why this was added in the first place since the tests fail without it when adding a new execution success test.

It was added in #4422, although there's no note of it in that PR so I'm assuming it was added by mistake.
