"public" just publishes the variable binding.  The binding does not need
to get published to be accessible to functions in the same source file:
the binding is only needed when the functions referring to it are
_defined_, not when they are being used.

Of course, you can't do session management on a variable you can't even
access, but publishing the variable for everybody else to tamper with is
not going to make our problem smaller.  So we need to be able to do
session-management on the variable _without_ publishing it, and that
means in the module where it is being defined.  And the easiest way is
to have separate defining commands for that purpose.
