I think that variables referenced within the loop conditional are
considered local
I've seen this is some languages -- Fortran, Forth, _javascript_? Java?
the inner just opens a new local scope
I wonder what happens if you declare the var within the conditional.
If you want to get to the outer variable:
1) Use a different variable
2) set another variable, say outeri = i; before executing an inner
I think it is a feature, not a bug.
If that is what is supposed to happen, then it might make sense to use
the same variable (for clarity) within a deeply nested set of
conditionals -- instead of i,j,k,l,m....
One look at the code would tell you that the redundant variable name
applies to this level only -- not an inner or outer level.
That's my SWAG!
