Now that 5.1 allows access to unnamed varargs via "...", you may argue that
it'd be better to map
	dofile(f,a1,a2,a3)
into
	loadfile(f)(a1,a2,a3)

But perhaps it'd be simpler to just do as you suggest -- people needing
to pass arguments to chunks could use
	loadfile(f,path)(a1,a2,a3)
directly (and be clear about it).
