nonlocal fails ?

Michael,

I think I did - though implicitily.   What do normal people use "by 
reference" arguments for ?   Yep, that is what I wanted too.

I'm trying to learn how Python works, and for that I (ofcourse) compare it 
to other languages.   What-and-how it does something different (or equal!) 
in regard to them.

I made propositions to its functioning ?    And I was thinking that I just 
pointed out oddities in it ...

> If you mentioned what problem you are trying to solve

1) Have value
2) use value in procedure 1
3) use updated value in procedure 2
4) use again updated value in procedure 1, 2 or maybe 3

For the sake of learning I'm now going over all of the possibilities to see 
if and how they work.  For that I've already excluded globals and the 
practice of feeding the value as an argument to the procedure and than store 
its result as the new one.  I've also excluded using a class object and put 
the code in there, as well as faking a "by reference" passing by using a 
tuple.   "nonlocal" looked to be another option, but it appears to be rather 
limited in its application.

In short, the /ways to the goal/ are (currently) important to me, not the 
goal itself (I'm sure that apart from the "nonlocal" one all of the above 
are viable, and I thus can get /something/ to work)

Yeah, I'm weird like that.  Sorry.
