The class types for std::decimal::decimal32 and friends do have the proper modes. I suppose I could special-case aggregates of those modes but the plan was to pass these particular classes (and typedefs of them) the same as scalars, rather than _any_ class with those modes. I'll bring this up again on the C++ ABI mailing list.
You could special-case this in the C++ conversion to generic by having the std::decimal classes decompose to scalars immediately.
