I haven't followed this closely, but don't see a problem with
not being symmetrical here. The C++ Middleware Writer (CMW)
has asymmetric support for Boost Range types:

@out (boost::sub_range<std::vector<int32_t> >)

If you omit the @out or write @in on that line, the CMW
gives you an error message that ranges don't support
receive (input) functionality. It only made sense to me
to output via a range so that's all that's supported for now.

I'm happy Adele won all those Grammys.  She deserves them
