The latter, yes. Since modules are bound in the scope chain, they're already
available for use as values.
This makes it very convenient to reflect them as first-class values:
var x = Math;
alert(x["sum"]); // function(x,y) { ... }
alert(x["thisIsNotDefined"]); // undefined
But since module instance objects are immutable, it's also easy for
implementations to make static uses, such as your example above, as efficient
as if they had been explicitly imported.
