I've attached a paper I've written for the upcoming Denver SG15 meeting and the Belfast meeting.

Abstract:

The changes to import in [P1703r1] were both too much and not enough to enable fast dependency scanning via partial preprocessing. It made import at the start of a line anywhere in the program an import-keyword, breaking things like import->doImport();. Also, no similar changes were applied to module. This paper fine-tunes the context-sensitivity of import and module, applying the fixes discussed on the reflector.

I've attached a minor revision (D1857r0.1).  We recently were able to cut the scan time down to 3s.

I received some wording feedback and have yet another update.  Now (D1857r0.2) which contains minor wording changes.
