Andrzej Krzemienski:
But even that appears like a non-obvious thing to me. Would other people here in the list, and also developers in general agree that it is ok that you have output operation but no input operation? I think that in the standard library they always go in pairs. (I am not sure, though).
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. -- Brian Wood Ebenezer Enterprises http://webEbenezer.net I'm happy Adele won all those Grammys.
