Our .gitlab-ci.yml contains a lot of super-repetitive lines like this by now:

- for example in examples/*/; do
    if [ "$example" = "examples/upgradeable-contracts/" ]; then continue; fi;
    cargo fmt --verbose --manifest-path ${example}/Cargo.toml -- --check --config=license_template_path="";
  done
- for contract in

I'd like to be able to run commands on all lines of a file. For example, bsed wrap lines with " should execute on all lines of the file. Current workaround is to include some trivial filter like wrap lines containing '.' with "

The test suite is currently somewhat weak with respect to testing error cases and validating the resulting error messages.

The test suite should probably move tests that check error cases into a separate directory.

PrimitiveType returns string:
    'string' | 'number' | 'boolean' | 'Date' | 'bigint';

• Validate bigint as a return type of terminal rules
