Bug 2495 – const syntax for member functions needs better description

The syntax for declaring const member functions is not very clear. There is no grammar. You need to infer from various examples what to do. For instance: class B {} class A { B x; const B getB() { return B; } } doesn't compile, because this is a const function returning a nonconst value. I had to find the answer on a forum. It's challenging to figure this out from the docs: class B {} class A { B x; const const(B) getB() { return B; } } Examples covering more use cases would probably help, as well as more formally describing how const is specified. Perhaps modifying the example of an invariant member function to return a value (other than string) would help.
