You can define multiple functions like this:
function f1 f2 f3 f4() {
  this body is shared by functions f1 f2 f3 and f4
}

and you can copy them like this (somewhat newer feature)
functions -c f1 g1

so if you can get all the function names in an array, you could just say:
task_func_names=( $(script to pull names out) )
function $task_func_names() {
  task_wrapper.pl $funcstack[1] "$@"
}
