Well, at that point, you're completely out of luck with regards to overloading !. In general, D doesn't really support overloading operators in a manner that doesn't match how the built-in types work. It does things like assume that <, <=, >=, and > will act the same way that they do with the built-in types and uses opCmp to extrapolate all of those operators. In some cases, you _can_ make overloaded operators return types that make it so that they don't function anything like the built-in types (e.g. opBinary with + could return a completely unrelated type that had nothing to do with the original type or with addition), but in pretty much any case where the compiler can get away with using the same overloaded operator for multiple operators, it does it. So, a number of decisions were made to better support correctness with types that actually try and overload operators to match what the built-in types do without caring about how that would affect types that would try and overload them to do unrelated stuff. - Jonathan M Davis
