So (**IMHO**) if that's really the case, we should really spend some

This is mostly about the design of object initialisation.
good idea or no?
Certainly.
My initial instinct would be to require a "const constructor" in order
for an object to be const-able, but I'm not sure if that would work
correctly or not..
Come to think of it, that would play REALLY nicely with 'scope' -- a
reference to a non-const object can be escaped from a 'const
constructor' if and only if the reference is scope!
Bingo! Does that work??
Yes, but it requires proper enforcement of 'scope'.
- which is undecidable/must be done conservatively
- code would have to become 'scope correct'
