One thing to note what it doesn't do - it doesn't produce a "module" scope. As
far as I can tell, the symbols in imported modules all go into the global scope.
It seems to be mainly a way of legitimizing precompiled headers.
It's better semantically than precompiled headers because you're importing
symbols only from the modules you import, not those from modules imported
indirectly. Just that would be an incredible cleanup.
I know. I just pointed this out as I suspect this will not improve compile times
more than precompiled headers do.
It seems there are actually two models: you can make modules from existing
headers (by writing module maps), or you can create modules directly by starting
your .c/.cpp file with "export <module name>;" as can see on the Writing a
Module slide. The former approach is introduced as the transitional model, the
later as the futuristic one that requires no headers.
They could dub them ".ci" files <g>.
