--- Comment #1 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
confirmed, looks like the -Wunused-function warning doesn't notice if the
address of a function is taken.


One surprising aspect of this 'trick' of taking addresses of functions is that
it makes private procedures of modules available/callable outside of the
module.
