I think this is an absolutely terrible idea, unless it has an "I know

void cFun(int* a, int* b);
What if it was allowed if the parameters were explicitly marked scope?
void cFun(scope int* a, scope int* b);
I can imagine it being a proper inconvenience most of the time though,
with many libraries not escaping a lot at all, you'd have to mark pretty
much everything scope manually.
Exactly. Using scope has been part of the discussion, and our agreement
was that it would be a lot of burden to require manual scope annotations
for non-escaping parameters.
