Hi, @knrc!
Thank you so much for this PR. We appreciate your contribution!

I observed that these changes lead to an unexpected result when running the expression below against URLs example:

{
    'scheme': url(object.href).getScheme()
}

Maybe it is related to the JSON serialization mentioned in the PR #15 (with protojson library).

Would you mind taking a look please?

@matheusfm fixed, it was a javascript error. I was missing a stringify call.
