Things could change, but IIRC it was called on unions and it was supposed to be called on unions, because unions are represented as an ADT with a single "variant".

In that case the name is misleading and the doc comment is wrong. I'm now auditing all callers to see whether they might be using this on unions. Depending on results I might change the doc comment and possibly the name.

Alternatively, introduce another method that does the same thing for unions (if union code wants the helper method but there's no code that needs to work on structs and unions).

I'd expect most code using this is common for structs and unions.

Yeah there's a bunch. non_enum_variant it is.

Note: this is technically a separate function that was caught up in the mass rename, but the rename fits here as well IMO.
It is also intended for use with unions.
