To me knowledge, the unary '+' in D is essentially a no-op (much 
like it is in Java). Mimicking C promotion rules might help new 
programmers coming to D from C or C++ feel more familiar with the 
language. The caveat here would be that the unary '-' operator 
would need to also perform a similar promotion for consistency.
