I can't say I would appreciate having to write

uint a = 0xFFFFFFFF;

or the equivalent for ulong.

uint b = 5;
uint c = -b; // error
int d = -b; // ok
auto e = -b; // e is type int

In the case of literals, I think allowing - on a literal should require
that it be assigned to a signed type or involve a cast.
