Re: Is there a way to set a var above it's current scope?

Yes I know, also one can use local at global scope to have the same effect as typeset -g there, this is a direct effect of how scopes are implemented.

You might be confusing it with the fact that `typeset -x q` is
equivalent to `typeset -gx q` and `export q` when used within a
function, even though normally `typeset` within a function is
equivalent to `local`.

If there is a variable in function scope, there is no way to do
anything with the identically-named variable in global scope.


    () {
      local q;
      # Nothing you can do here will have any
      # effect on the global `q`.
