That it wasn't clear to begin with.  People associate radically
different things with the word "module" or "module system":

- configuration management
- interchangeable parts
- namespace management
- hygiene
- encapsulation
- separate compilation
- independent compilation
- optimization
- ...

Some of these goals conflict, at least among the module systems and
designs we've looked at, which is why we (eventually) narrowed down
the list of requirements.  I'll be happy to elaborate, but it's a long
tortuous story ... :-)

No.  The PLT module system has obvious differences to this one.  This
one most prominently has static dependencies and static (if implicit)
interfaces, which PLT's MODULE does not.
