You don't, it's an orthogonal concern. Note that Sam was *not* arguing against the existence of lexical modules.
But it's not nearly as important as the rest of the core system -- as Sam describes, coordination and separate development are the most important piece that the module system needs to address. We dropped lexical modules mostly in the interest of working out the core and eliminating parts that weren't necessary for ES6. Kevin's been urging us to reconsider dropping them, and I'm open to that in principle. In practice, however, we have to ship ES6.
But let's keep the question of having lexical *private* modules separate from this thread, which is about Andreas's suggestion to have lexical modules be the central way to define *public* modules.

No, it would be too hard to get this expressive enough to satisfy the web platform's polyfilling needs.
