I've often thought one of the biggest wins that would seem to affect
my code would be comprehensive value range propagation.
assert's and contracts can give value range information to the
compiler, also comparison statements, bit masks, casts, etc, can
truncate the possible value range, which can create many opportunities
for optimisations. It would also be really nice to eliminate errors
associated with down-casting.
I'd be very interested to see the frontend using (more) information from
asserts/preconditions to optimize code. There's a huge amount of potential
there.
