Sometime on Oct 9, Mark Stosberg assembled some asciibets to say:

Simply put, when you pass the subroutine definition to the param
function, you're passing a reference to the subroutine. The subroutine
does not get executed at that point. From the perlfunc man page:
Without a NAME, it's an anonymous function declaration, and does
actually return a value: the CODE ref of the closure you just
created.
You should define your function elsewhere, and just call it from your
param:
param(my_loop_var => &function);
sub function {
...
}
