For what it's worth, that's my conclusion too.

(Guards and booleans are a bit of a mess anyway, with
three somewhat different and/or operations, two sets
of guards, and so on. The joy of backwards
compatibility, I guess ...)

(And when the dust has settled, we still didn't get
general guards ... Yes, yes, I know. The language
designers like guards just the way they are.)

Best,
Thomas
