Support interface types as enum variant fields

[jplatte]

It would be nice if I could use an interface (object) type as a field of an enum variant. Currently, this failes with:

thread 'main' panicked at 'Building the UDL file failed: Failed to parse UDL

Caused by:
    Objects cannot currently be used in enum variant data', my-crate/build.rs:2:57

I faced the same issue, is it something planned to be supported ? could I help on it ?

I don't think anyone plans on working on this, but we'd certainly look at a PR!

Is there anything new on this?
