	These do not do what you think they do...

	"global" is used INSIDE of functions (def) to specify that references
to the name on the inside MUST access the module level name.

	Note: read-only access does not need "global"; only bindings to the
name (assignments) have to have the "global" otherwise they define a local
name.
