My worry is avoiding apparently reasonable requirements which may not
be realizable within the context of Standard C++.

Several past proposals were dismissed by the C++ committee without
real consideration because they relied on behavior outside the scope
of the C++ standard. Thus my interest on avoiding such outside
behavior where possible, and relying on some other ISO standard as a
fallback.

I'm probably just being fussy.
