How to generate a non-const method from a const method?

Question

While striving for const-correctness, I often find myself writing code such as this

class Bar;

class Foo {
public:
  const Bar* bar() const { /* code that gets

I've also felt this pain before -- in essence, you're trying to tell the compiler that constness "propagates" through bar(). Unfortunately, as far as I'm aware, there is no way to do this automatically... you'll just have to write the second version of the function by hand.
