Sure, but is that worth 7 to 9 extra characters at every single use site for something that's actually pretty common? Is it worth the muddled mess of an all-lowercase keyword with no obvious break, or the attention-grabbing of a capital letter or an underscore?
`module` and `file` are not going to be obscure corners of the language. Most people will probably learn about them at the same time they learn about `public` and `private`.
(Actually, if `module` continues to be the default, you probably won't see it *that* often. You *will* see `file`, but that's the one that can't be as easily confused with a declaration.)
Obviousness for new users is great, but you can take it too far. We call the type `Int32`, not `SignedIntegerBetweenNegative2ToThe31stPowerAnd2ToThe31stPowerMinus1`—and if we did, it's not clear the longer name would really be more obvious, because it would be such a pain to read.
