The compiler swallows opDispatch errors

Well my rule would be if opDispatch is considered, the error 
shoudl be printed.

But you can prevent opDispatch from being considered by putting a 
constraint on it.

So

struct A {
   void opDispatch(string s)() {
         dfsdfsdf;
   }
}

A a;
a.whatever; // REPORT THE FULL ERROR OMG


BUT


struct A {
   void opDispatch(string s)() if(s != "whatever") {
         dfsdfsdf;
   }
}

A a;
a.whatever; // "no such property: whatver"


so you only get "no such property" if the opDispatch is not 
considered at all because the outer constraint filtered it out.
