How do you prevent someone from defining the member function out of line? Even if you could do it, it seems prone to subtle bugs.
- I understand but I would be interested in a solution even if it had limitations. In this specific case, even if the solution was to only work when the member function is defined inline within the class, I would still be interested in it.
However, even for inlined member functions, personally I could not come up with any code that I can program within the member function definition scope which has an effect that can be inspected at compile-time at the class definition scope...
Even if it could be done on some compilers, it wouldn't be portable because there's a good chance that the compiler won't try to compile the member functions until it's finished with the class body. Try compiling this class C { void f() { int i = ::test; } static const int i = ::test; }; The first error is likely to be for the class member rather than inside f. In Christ, Steven Watanabe
