I have a philosophical objection to having unused arguments.  It
comes from many years of compilers and lint complaining about
unused arguments (so much so that I have a standard

#define NOTUSED(x)  (x=x)

to satisfy compilers - it's usually optimised out but generally
after it has suppressed the warning).
