Requires, Exports, and Provides

[Paul Benedict]

Tim,

You made an interesting analogy regarding the "import" syntax. I was
thinking about it... If you really want the module syntax to fit with
current syntax, the keywords should be in the imperative form: require,
export, provide. The ending "s" should be dropped.

Cheers,
Paul
