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.
