Callable modules are a hugely important use case. jQuery and Underscore spring
to mind. I’ve made one myself [1].
Also important: what about construct-able modules? Or to put it another way,
what about exporting a module that is a class? Examples from Node [2] [3] and
Node-land [4] [5] are abundant.
It makes me think a more generic mechanism would be required to export any
arbitrary object as the module itself. Perhaps
export module as function jQuery(selector, context) { … }
// or
function jQuery(selector, context) { … }
export module as jQuery;
export module as class Runnable { … }
// or
class Runnable { … }
export module as Runnable;

Subject: Re: simpler, sweeter syntax for modules
One point that I haven't seen mentioned yet (and it is unrelated to syntax):
"export call" makes me cringe -- making modules callable is not just weird, it
seems completely future-hostile to the possibility of having parameterized
modules. I don't think it is worth bending the notion of module like that if
all that is gained is minor convenience.
