I don't know what the common definition of it is, but I'd define it as the 
complexity of the code goes up linearly with the number of lines. I'd say the 
close the complexity is to linear, the better it "scales".

I'd then define complexity as the number of interactions between the lines of code.

This means that the better a language supports encapsulation, the more scalable 
it is.

For example, if a language has only one namespace, the larger it gets, the 
harder it is to declare a new variable, as it would have to be unique. This 
would be a quadratic increase in complexity as the number of declarations increased.
