I seriously dislike this solution, especially for the most frequent
case of unused parameters --
not only it is a hack, it also does not work while compiling from command line.
I would much prefer either {$UNUSED var} compiler directive, or, failing that,
Unused(var) library call -- similar to what is done in TAChart.
