If a, b[, n] are used a lot in a context where they need not be methods
of an object, it would seem futile (and – depending on the number of
calls – quite inefficient) to me to call them as methods of an object
nevertheless.

You don’t say (I suppose creating a superfluous function object is
justified by not resolving those pesky identifiers first :^)

That’s the problem of all artificial example code. In the origignal
code, calling a function expression that does nothing but returning an
object was unnecessary, too.
