Well, the point behind having hidden variables is that the source code which needs to use 
a hidden variable can just call _do_setenv() (or whatever) and have it set an environment 
variable that is hidden.  My preference would be that any variable that starts with a dot 
(.) is hidden.  That way, the source code doesn't really need to have a separate list.  It 
just names its variables with a dot.  The rest is automatic.
