I have a function. Let's call it 'my' for instance. I want to have define another function that sits of top of the original and acts in the same way, let call it 'our' for instance.
Readers of my previod post will know where I'm going with this.

I don't want to open a debate about when 'our' should or should not be used. I just want to create a fake 'our' function that can be used in older versions perl that is actually my.

I despirately need code that looks kinda like:-
unless (exists ${our}) {
  ${our} = \${my};
} ## End unless

I know that code is wrong, but you get the idea. Please help. I need to patch this very large and widely used script ASAP.
