seems reasonable

As for the term "nesting" - I was using it in the sense that 
fnA() calls fnB(), then anything declared in fnA() should be 
visible to fnB(). At least that was my understanding from a 
long time ago. However looking in google for "wiki" and 
"nesting", I find the term nesting is used only for 
recursive calls by a fn() to itself. I have no idea whether 
I missunderstood nesting when I first heard it, or the 
meaning has changed over 40yrs.

Writing a fn() inside another fn() apparently is called 
enclosing in python, although nesting would seem to be a 
reasonable term for it.
