The other thorny issue is that lambda expressions aren't Assignable, because their operator= creates a new lambda exression instead. This might well be unfixable.
We could make lambdas Assignable by defining the ordinary assignment operator when the rhs has the same type as the lhs. That would rule out strange lambdas like "_1 = _1" , but I don't see that as a huge loss.
I think that's a good compromise.
I support Joel's approach of deprecating the old lambda interface and migrating folks to phoenix.
I've always thought that the plan was for Lambda and Phoenix to merge one day.
That used to be the plan, long ago before Joel came to fully appreciate the subtle differences between the two.
Apart from that, I'm not a Lambda user, so I don't have an opinion. :-)
Even your non-opinions are valuable. :-)
Peter, you rock! I highly value all your opinions. Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net
