Let me put it this way: I can't think of a good reason why
global:send/2 should ever need to first pass the message to
another process, instead of just performing a lookup followed
by a send (note that the lookup can be arbitrarily complicated
and involve any number of messages) - especially since it would
lose the nice ordering property and possibly break some existing
applications. So I think that it should be safe to actually put
this guarantee in the documentation for global.
