Thanks for the thorough explanation. For now, I am keeping a function
instead of a def. But, as you say:

Yes, use block-local, function-local, or script-local variables. Those
don't need any explicit scope.

Move the `i` variable in the script-local namespace. That is, don't
declare it inside the function, but at the script-level. You can still
reset it to a default value whenever the function is invoked:

The MetaPost plugin in Vim contains the following definition to replace
the n-th occurrence of `beginfig(...)` with `beginfig(n)`:
function! s:fix_beginfigs()
let i = 1
g/^beginfig(\d*);$/s//\='beginfig('.i.');'/ | let i = i + 1
endfunction
command -nargs=0 FixBeginfigs
