Negating version is not the main problem, as one can do version(x){}  
else{}, which is ugly but effective.

Logical AND is also quite easy with version(x) version(y) {}

The one I would really like to see is logical OR. There is no easy way  
around this, one must come up with convoluted mechanisms that are much  
harder to design, write, and understand than just version(x || y)
