I suppose it's because there's no need for type extension or dispatching
calls.  So why pay the overhead?

A different question might be: Why is the prefix notation not allowed
for untagged types?  I don't know the answer to that, but it's probably
documented in the relevant AI.

I'm not a big fan of prefix notation, by the way.
