That will be very handy of course and some users may heavily 
demand it, but at the before-ImportC times, when I dreamt of 
having a C frontend integrated with D compiler, I assumed it'd be 
good enough if I could just write a one line wrapper function in 
the C file to call the ugly macro, for anything that's not 
auto-convertible to plain enum constant.
