According to joare@sdata.no:
>	return f() || g();

Perl also has the LISP meaning for this operation.

This C equivalent is too verbose:

>	a = f();
>	if (a)
>		return a;
>	else
>		return g();

Try instead:

        return (a = f()) ? a : g();

Note that GNU CC has a ?: operator where the second operand defaults
to the value of the first operand.  So with GNU CC, you can write:

        return f() ?: g();
