I'm afraid that would not only break most D programs, but also
interoperability with C.
Could you explain this? I didn't think we used 'real' to
interface with C at all. We might need a type to match 'long
double' in C, but what that is is already exceedingly variable.
This would probably be another case for a special alias like we
have for c_long.
