Patterns of dynamic scoping and nested routines.

[Steven W. Orr]

It has been an exciting weekend for me. I studied the dynamic vs static scoping 
rules and I think I have a better handle on things, but I have a few questions.

It seems that there's no reason why we are not allowed to write nested 
functions. Nested functions would not be visible to other functions, and might 
be a way of providing capabilities to users to specify *when* they want to have 
static scoping.

So between nested functions, dynamic scoping and recursion, I was wondering if 
people have explored pattern usages that might be germaine to bash? Any do's and 
dont's? Any gotchas?
