"Nice"? I hate dynamic typing with a passion! It offers very few benefits
and only in very specific locations....


Anyway, dynamic scoping is where a variable name can refer to different
things based on where it is in runtime. The language walks to stack upward
to find the first instance of the variable. So a local variable in a calling
function can override a global name in the function it calls.

I've seen it in Common Lisp; I find it weird. But there's an example
