I have a Fusion sequence. I want to create an object of type T using the elements of the sequence as arguments to the constructor. Is there an easy way? I can't tell my looking at the docs. I looked at the stuff in fusion/functional and couldn't find what I was looking for.
Isn't that exactly what a Phoenix actor does?
Hartmut, are you saying this functionality has no place in Fusion?
I don't think we've got anything that supports this directly at the moment. Is the sort of thing you are looking for?
fused_ctor<T> fc; T t = fc(sequence);
Where fused_ctor::operator()(Seq const&) breaks up the sequence into args for the T ctor.
Yes, that's the thing.
If thats the sort of thing, I think we should have something like this, I can cook something up over the next few days, once I've worked through a bit of my backlog :)
Of course I may have missed an existing feature, which my co-authors might pick me up on...
Thanks, Dan. FWIW, I have my own solution for this now, so there's no rush. But I'm sure it'd come in handy eventually. -- Eric Niebler Boost Consulting www.boost-consulting.com
