Sure. But the code above I wouldn't really call "metaprogramming". It's 
simply an alternative to the standard way of adding new methods. If you 
don't like it, you'll actually have to reject the whole idea of dynamic 
classes.

But I do agree that metaprogramming should be used with caution (or 
maybe even avoided), since it can make the code hard to understand to a 
point where the behaviour is almost unpredictable.
