C code that returns error conditions, this is useful:

=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0ErrorCode err =3D some_= function();
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0err =3D err ?: some_oth= er_function();
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0err =3D err ?: some_thi= rd_function();


Me too, but since it was rejected in May of this = year, good luck =3D/

One way to get this would be to convince the C = committee, which would put pressure on the C++ committee.=C2=A0 That GCC an= d Clang already support this is important.
