Accessing the global handle through a subroutine makes it much harder to accidentally clobber it. (Further, it makes clear to anyone reading your code that $handle has a well-defined value that doesn't change, which is kind of nice for maintenance programmers.)

In general, I'm a big fan of wrapping related scope-specific variables in a singleton class, just because it makes domain control so much easier. This works best in very specific cases, where you don't see much potential for partial code reuse, because you're coupling all the code that depends on the singleton. It becomes correspondingly harder to pull out individual functions from that scope and use them elsewhere, because you have to pull out the singleton as well (which probably doesn't fit your new problem perfectly). In Biker's situation, this might be a good fit.
