D2.0 const this methods

[Daniel Keep]

This seems to work:

class Foo
{
    int x;

    const(Foo) getThis()
    {
        x = 42;
        return cast(const)this;
    }
}

Remember that "const Foo" is actually "const const(Foo)": a *constant
reference* to a constant Foo.  What you want is a plain old constant
Foo: const(Foo).

Your example is bad because "const int" by itself only really makes
sense as a declaration, not a return type: you're returning a const(int)
which doesn't do anything.

Does that help?
