Yes, I remember that.

What I wonder though is whether we can achieve the same thing as the
union but using propagated inputs instead.

Yes, but that’s OK (the ‘inputs’ field is “thunked”, so it can contain
references to not-yet-defined variables.)

I think propagated inputs would make things simpler since that would
allow us to remove the code that builds the union.

But it could be that I’m overlooking something, or that it wouldn’t work
for some obscure reason.

Could you give it a try to see what happens?

TIA!
