Dear all,

I have the following issue. I must build a wrapper subroutine around an existing subroutine. The "inner" subroutine whose code I cannot fiddle with may return different things, i.e. sometimes it returns a hash, sometimes a scalar and sometimes a list. After doing some other tasks, the wrapper must return the return value of the inner function. How do you suggest I handle this? 

sub __func__ {
#handle @arglist
if () {
  return %myhash;
}
else if () {
  return $myscalar;
}
else {
  return @mylist;
}
}

sub func() {
#some input
&__func__(@arglist);
#how can i handle different return values of __func__?
#some other stuff
}

Thanks in advance,

Athanasia
