sure, interpret "nuke" as a long term thing
(starting with deprecation, manpage notes, etc.)

Remapping f(a) into f(a, b) requires both a macro
and a wrapping function, something like this
T __f(T1 a, T2 b) { return f(a, b); }
#define f(a) __f(a, b)
Surely can be done (in fact, i have done it already, see
http://info.iet.unipi.it/~luigi/netmap/20120725-ipfw-user.tgz
but i am not so interested in participating to the IOCCC :)
