I didn't really mean dynamic typing (that's why I wrote "dynamicity" with question mark). To be clearer: the ability for things to change at runtime, i.e. for the programmer to do things like monkey patching. I guess dynamic typing is related to this, at least in the sense that you'll have to give up on some static typing in order to get more flexible dynamic behaviour. And yeah, I realize that Python et. al. is used for real apps, and certainly not just for scripting tasks.
