I haven't looked really closely at your code, but this looks fishy...

You've created a DynAny with the right type for the discriminator, but
it's not the union's discriminator...

Here you're getting the actual discriminator from the union.

And now you're setting the one that isn't the union's discriminator. It
doesn't matter because it defaults to that case.

Now you're setting the wrong thing again, but this time the default is
wrong.

I think it'll probably work if you rearrange the code so that edisc is
the union's discriminator, not some other unrelated DynEnum.

Cheers,
