I'm thinking the construct and new_ lazy functions will be particularly useful. Many of our classes end up in containers and or as output from transformed ranges, and end up with many bound static make functions replicating the constructor arguments. Phoenix "construct" makes all those "make"'s redundant. :)
I think, too, that those lazy functions would be very useful, and I look forward some way to express also placement new. Ideally, I would like to delay which version of new is called to the call site, so I would need a new2_ lazy function such that 'new2_<T>( _1 ) (x)' is still a functor with overloaded operator (), that can be called with 0 arguments (normal new behaviour), and with 1 argument (placement new), ...
Would it be generally useful to have a variant of "new_" that returns a
shared_ptr directly? Without it one would need:
Yes, I think this will be very useful.
Yes, and yes! :-) Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net
