I would hesitate to say "impossible" :)  Efficiency would clearly be
better than what we have now, though not the pinnacle of performance
(and is anything in Erlang the pinnacle of performance?).

I can certainly see the quirks in my proposal, and I don't ever expect
to see it in Erlang.  But I don't know if adding yet another basic
data type to Erlang is the way to go.

Not any more than you have with "1 + ok".
