The driving forces behind lambdas for C++0x are Jeremiah Willcock, Jaakko Jarvi, and Valentin Samko.
RD> I'll keep an eye out for papers from them. Currently there are two lambda proposals, one from me and another from Jaakko and Jeremiah, et al. The main reason we have two proposals is that we did not know about each other's proposal until the final drafts were ready. The main difference between these proposals (apart from minor syntactic differences) is that in one the local scope variables are copied by reference to the lambda object by default and in another they are copied by value. There are advantages and disadvantages in both approaches. We are currently working on resolving issues raised during the committee meeting and hopefully will write a new paper on lambdas. Any feedback on this topic will be highly appreciated. Valentin Samko http://val.samko.info/
