Or Network.Protocol.Tcp.Server.Http? Or perhaps
The argument I was trying to make is for some sub-module hierarchies (e.g.
HTTP) the word "network" communicates very little information and is thus
superfluous. Also the deeper we make the hierarchy the more difficult it is
to navigate it. Where would you expect to find a HTTP server module?
Here are three possible "answers":
Network.Protocol.Http.Server -- How is a server a protocol?
Network.Web.Server -- HTTP is a protocol that doesn't necessarily imply
Network.Asynchronous -- This is an implementation detail.
Or even worse, an HTTP server might not live in any one module making it
difficult to find all the pieces you need for your current *task*.
Control.Server -- runServer
Network.Protocol.Http -- sendResponse
I'm not convinced programmers think in these hierarchical terms at all when
programming. More likely the thinking is task based than anything (although
I need to find some evidence to support this view).
Also consider how many tokens you need to read when scanning e.g. an import
list to find the relevant parts:
Furthermore, if to module imports always co-occur I think the module
probably would have made more sense as one module unless 1) that would
result in one huge modules or 2) that is not possible because of name
If we move everything up to the root then the root will be even more

Yes, a bit.
P.S. The module reorganization effort surrounding Python 3.0 might be of
interest for people in this thread.
