I have a problem which seems simple, but I haven't found a solution to it
yet.

Let's say I have two packages, A and B.  In a subroutine of package A, I'm
trying to return a reference to a subroutine in package B.  So in package A
I have:

my $refToB = \&B->someFunction;

But that gives me the error:  "Undefined subroutine &A::someFunction."
This also doesn't work:

my $refToB = \B->someFunction;

That one returns a reference to B->someFunction AFTER it has been evaluated
with no arguments.  So if B->someFunction() returned "0", $refToB would be a
reference to a scalar containing "0".

Help would be greatly appreciated.
