Yes, you're right. However, there's one additional wish -- I'd like an
appraoch different macroses for different functions. E.g. for POSIX calls I
only encounter -1 returns and NULL returns for error reporting. So I'd like

   int tty = check(open(check(ctermid(0)), O_RDRW);

to work. I guess this could be done by providing two overloads for the
'Wrong' function...., but not, the 'Enforcer' template only works for
specific type of return value :-(
