The moment something in Lua is not elegant, it usually means that
one should not be doing it that way.
I can think of only one unavoidable application for select("#", ...),
unfortunately one for which an example is to be found in the standard
library (table.insert), and that is when the calls
involve different semantics for a and b.
A beginner of Lua would do well to avoid writing such functions.
