This has been proposed several times before, it was also proposed for C++0x. The 
difficulty is it makes having a ; or not substantially alter the semantics. The 
history of these languages is that the presence or absence of ; can be hard to 
spot, as in:

    for (int i = 0; i < 10; i++);
       ... do this ...

which has cost at least one expert developer I know an entire afternoon staring 
at it convinced there was a compiler bug because his loop executed only once.

(And this is why D disallows this syntax.)
