           Summary: Static modules, aka enforcing static import.

I find myself using the very nice static-renaming-import scheme to provide namespacing capability.  For example, rather than have a module full of database functions with, for example, a 'db_' prefix to avoid collisions, its useful to just use 'static import Db = foo.bar.Db;' and call all functions via 'Db.func()'.

Since some modules are tailored toward use in this way, I feel it would be nice to have a way to specifically enforce our module being static-imported.  The proposal is simple enough: allow the 'static' attribute on 'module' declerations, with the meaning that any corresponding 'import' must also be 'static'.  Example:

-----[ foo/bar/Db.d ]-----
static module foo.bar.Db;

void func () {}

-----[ fred.d ]-----
import foo.bar.Db; // <- Error: import for module 'foo.bar.Db' must be static

-----[ greg.d ]-----
static import foo.bar.Db; // <- Ok


Naturally, static-modules should still play nice with renaming imports and selective imports.

I think static import should be the default, and there should be an explicit way to import everything, not the other way around.

Since D is supposed to prevent symbol hijacking I don't see much benefit for this. If the user has conflicts he will use one of several techniques such as using static imports, using aliases, using renamed imports and/or selective imports.

I don't see why you would force a module to be imported one way or another. It seems like a sure way to make importing modules annoying for the user.
