So how about

Sure.

I think the ideal behavior for these suffixes would be to treat them as
user-defined literals if a corresponding literal operator is available,
or use the built-in extension if not. But that doesn't need to happen now.

I thought about that.  We'd need some machinery that would allow cpp to query 
what has been declared already.

Or alternately, always treat them as user-defined in C++ mode and have the front end decide to use the built-in interpretation if no literal operator is declared.
