Is the sort of thing you are looking for?

fused_ctor<T> fc; T t = fc(sequence);

Yes, that's the thing.

OK, but why duplicate the unpacking of the Sequence?

All it takes is yet another adapter encapsulating a type's ctor(s) in a function object to just use fusion::(invoke|fused)_function_object. E.g:

<snip>

Client code (at function scope):

invoke_function_object( ctor<my_class>(), argseq );

Yes, that's exactly it. Now, put it in Fusion so I don't have to write a function object with N overloads. :-) -- Eric Niebler Boost Consulting www.boost-consulting.com
