I was trying to create my own module system and wanted to leverage the
existing infrastructures of eval and namespaces.  Since each module
basically has its own namespaces and I did not want to have to create a
brand new namespace for each module (so that way the structs and parameters
are not evaluated multiple times), hence I was seeking a way to duplicate
the namespaces.

If the above thought process is not exactly how it works, please let me know
too. Thanks.
