using namespace std;

Mark all my class by __attribute__((warn_unused)) and all my colleagues was
hate me.

Support disabling forwarding via #paragma please.
There is a lot of noise in the log if you include huge generated files.
An example can be taken in the github project F2I-Consulting / fesapi.
