Not polluting the global namespace.

Ensuring the function can't be called from outside a function.

It's a trite example, but I do something like:

sub gvim () {
 array orig_args=($@)  gv_files=() gv_ops=()
 int use_tab=0  look_for_ops=1

   sub _exec_gvim() {
     array args
     ((use_tab)) && args=("-p")
     (( address@hidden:-0} )) && args+=(address@hidden)
     (( $# )) && args+=($@)
     command gvim "address@hidden"
     unset -f _exec_gvim

AFAIK, _exec_gvim, can only be called from within "function gvim", no?
