At the very least, _implicit_ conversions should not lose data,
i.e. a  A a1;  B b = a1; A a2 = b; round trip ideally should yield 
a1 == a2.

If I am ready to give up information, I'd like to need to say so 
in the code explicitly. (And yes, part of the deed is done in the
core language, but even there compilers start to nag about it.)
