The code below prints the uid as expected from within the foreach loop. However, it will not print it in the subroutine. Why not and how can I fix it?

The reason is that the foreach loop localises $uid; but the subroutine mail closes over the variable declared above and outside the foreach loop, which is never initialised or assigned to.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
