Fixes #3362

@T4rk1n , is it possible to generate a tarball with a prerelease with these changes? Would facilitate testing early.

This PR looks great to me!

I actually ran into an error like the one reported in issue 3362 when I was working on DMC recently. It failed during the build with this message and I was stuck.

ERROR: "__@iterator@3570" matches reserved word pattern: /^_.*$/

To test this PR, I checked out that failing commit in DMC and tried it with this solution. There was no error message like the one above during the build, so I could take the next step and run the tests. I was able to see this helpful error message. This PR would have saved me lots of time!

        args = {k: _locals[k] for k in _explicit_args}
    
        for k in ['fontsize', 'length', 'localeCompare', 'match', 'normalize', 'search', 'split']:
            if k not in args:
>               raise TypeError(
                    'Required argument `' + k + '` was not specified.')
E               TypeError: Required argument `fontsize` was not specified.

@ndrezn do you need any other scenarios tested?

I don't recall actually why I wanted early testing on this 🫠
