I agree with the @ is ugly and # is ugly, but I believe @safe, 
@nogc and @property should have been keywords.

A personal opinion of mine though is that @safe shouldn't have 
existed and should have been the default for functions, where a 
@unsafe should have existed in its place.

That's a design choice ex. Rust does better than D. It provides 
safety by default, where in D you have to enable safety.
