ignore_unused_variable_warning is defined in workaround.hpp, so I may be
wrong that void casting stops the warning everywhere. (usage warnings
are pretty fiddly). However, that method works by not giving the
parameter a name, which I seem to remember getting warnings for in some
compilers. (some versions of GCC?)
