Well, I guess you can say that every new name creates a new scope 
as it shadows the outer scope in order. Anyway, a prototype isn't 
a bad trade-off.

(Btw IIRC «dynamic scope» is a completely different concept, that 
means the lookup is done down the call-graph. E.g. if function 
f() calls g() and f() has ```x```then g() will access f()'s 
```x``` when mentioning ```x```.)
