My knee jerk reaction is that it's a very bad thing that "new"

Actually, in addition to user defined overloads (which are
deprecated, granted), `new` also can mean stack allocation
already! See the `scope` storage class and scope classes.
I don't agree as you have to add `scope` for the class to be
allocated on the stack.
The language is free to optimize `new` as it sees fit. (IMO,
that's the only real justification for it even being a built in
language feature instead of an ordinary library function.) The
real changes in this proposal are:
Yes, but it must be done in such a way that a user never knows
the difference. I have my doubts about whether replacing all heap
allocations in `throw new` expressions will be as transparent.
Actually it's already not as there are restrictions on catch
blocks that catch refcounted Exceptions.
