When you try to use type inference on a const member function, you get a
compiler error:

class Foo
{
public:
    auto foo() const { return 0; }    
}

Compiling gives:

test.d(4): no identifier for declarator foo
test.d(4): semicolon expected, not 'const'
test.d(4): Declaration expected, not 'return'

Removing the 'const' allows it to compile, but the function can no longer be
called on const objects.

The same applies for structs and @property methods.

This is using DMD 2.049.
