Hi,

I today found remarkable bug:

int k = -1;
uint n = 7;
assert(k < n);


Code above should execute without proble, but dmd it computing false as value
of (k<n) which absolutly nonsensical. casting n to int, resolves problem

int k = -1;
uint n = 7;
assert(k < cast(T)n);

How it can be so long time not resolved?
