Another feature request: it would be nice if parameters<> were a valid MPL sequence that I could manipulate with MPL algorithms. It already is an MPL sequence.
No, it's not. An argument pack is an MPL sequence, but a parameters<> instantiation is not.
Oh, I see. What would you use that capability for?
I'd use it for the generic object construction utility I sent mail about a few days ago. The constructor parameters for facade<Object> should be the constructor parameters for Object, plus any additional parameters facade<> might need. So I need to be able to manipulate Object's parameters<> at compile time.
So essentially, you need to construct a new parameters<> specialization with additional -- or fewer -- ParameterSpecs? I think it's a fine idea, but I have to say, we're up to our eyeballs in work to do on the parameter library right now. So I guess you should either put it in the tracker for later, or as ever, contribute a most welcome patch. -- Dave Abrahams Boost Consulting www.boost-consulting.com
