I have an exported function. In this function, there's a call to another function (which is not exported). This other function resides in the program that uses the exported function. However there is also a function with the same name in the module that exports the function. How do I make the exported function call the right function (the one in the caller's namespace)?

Here's an example of what I am talking about: 

package TT;

use Exporter;
@ISA = qw/Exporter/;

@EXPORT = qw/s1/;

sub s1 {
  print "s1";
  s2();
}

sub s2 {
  print "s2";
}


1;


perl -wle 'use TT; sub s2 { print "NO S2!"; } s1();' 

output:
s1
s2

I want: 
s1
NO S2! ?
