This diagnostic bring headaches because frequently `-Wunused-variable` 
suppression is done via no-op pseudo-consuming function like 
`boost::ignore_unused` 
<https://www.boost.org/doc/libs/1_73_0/libs/core/doc/html/core/ignore_unused.html>.
 Particularly, it fires in Boost here 
https://github.com/boostorg/concept_check/blob/e69c81326d5a4359ac53f9c6fe53fc2baf24df50/include/boost/concept_check.hpp#L135-L141.
Is it possible to make the diagnostic not fire for empty body consuming 
functions?
