You're talking about something completely different.

In Perl they have:

  Net
  Net::Amazon
  Net::BitTorrent
  Net::FTPServer
  (and a million others[1])

The proposal is to have a hierarchy of OCaml modules, of this sort:

  Net
  Net.Amazon
  Net.BitTorrent
  Net.FTPServer
  (and a million more)

which doesn't scale.  However, using '_' as a separator scales because
distributed, loosely coordinated parties can add new modules ad hoc to
such a namespace.
