Downside here is, if you first implement it like this, everyone will
be used to that implementation. If after that a special syntax gets
introduced, there will be people confusing it and having to use
multiple libraries which use the two different ways. And most people
will stick to the old way because it'll have more compatible python
versions, no matter how much better a new syntax could be. Unless you
want a deprecation cycle planning for a feature not even implemented
yet ?

I think that if implemented, it needs to be the final implementation right away.
