The template-based IDL will make this stuff easier.
Agreed.
Is there a non-macro-based variant of the IDL in development,
Yes, but I haven't had much time to work on it. See http://tinyurl.com/6w59y.

The names that I like:
IEmpty IAnything IUnknown INull
I find all of these distrurbingly reminiscent of COM interfaces...
I intended the reminiscence but not the disturbance. :-)
I would rather say:
FuBar(IAnything n) { if (n.type_info() == typeid(int)) { cout << extract<int>(n); } }
Whatever, this is trivial stuff, I don't really care that much.
I beg to differ, and I am sure many others will along with me :)
My preference is for 'unknown', since you don't know anything about the type.
FuBar(unknown obj) { if (target_type(obj) == typeid(int)) { cout << extract<int>(obj); } }
I don't really have a preference between "anything" and "unknown", but I would have thought the former would be less disturbing. ;-) Jonathan
