This PR is making two main changes to the Explorer and Toolchain: - Replace the `is` keyword in `where SomeType is SomeInterface` with `impls`, so it is `where SomeType impls SomeInterface` - Rewrite uses of the "impls" to something else to avoid, frequently "`impl` declarations" or "implementations", to avoid confusion with the `impls` keyword. --------- Co-authored-by: Geoff Romer <gromer@google.com>
