I'm exploring functional programming with vimL and immediately ran into
seemingly counter-intuitive behavior:
------------------------------------
function! Outer()
let outer_var = 0
function! Inner()
let outer_var += 1
endfunction
call Inner()
echo outer_var
endfunction
call Outer()
-------------------------------------
The result, when I run this from 7.1.156, is that 'Inner' reports
'outer_var' as
unknown. I was expecting '0' but would eventually like to have my 'Inner'
use 'outer_var' as state via dictionaries or some other mechanism. It's
disturbing that 'outer_var' is not available to 'Inner'.
Am I missing something? Is this the intended behavior? If so, where else
can I read more about scoping? I've been reading usr_41.txt and eval.txt.
