The local scope is the function body, while it's running. Your example does
not really demonstrate it. This does:
$ set KK 3
$ function foo; set -l KK 33; echo $KK; end
$ echo $KK
3
$ foo
33
$ echo $KK
3
Another way to introduce a scope is with `begin`:
$ echo $KK; begin; set -l KK 44; echo $KK; end; echo $KK
3
44
3
