Interview Update With Bjarne Stroustrup On C++0x
An anonymous reader writes "DevX interviewed Bjarne Stroustrup about C++0x, the new C++ standard that is due in 2009. Bjarne Stroustrup has classified the new features into three categories: Concurrency, Libraries and Language. The changes introduced in Concurrency makes C++ more standardized and easy to use on multi-core processors. It is good to see that some of the commonly used libraries are becoming standard (eg: unordered_maps and regex)."
No it's not. The standard does not define concurrency issues. Not how to spawn threads and create mutexes, but lower-level issues, like coherency. This is sorely needed for truly portable code. Rvalue references will help a lot with the creation of temporaries that are just copied and destroyed. You see this now in all the specializations in the libraries for the swap function. With rvalue references, you can write a single template that will be optimal for all types. Currently template error messages are a mess. several lines of unreadable garbage because your type doesn't supply a member or operator that the template needs. Concepts will lead to concise, easy to understand error messages. typedecl and the new use for the auto keyword will reduce verbosity, and stop the nightmare that is figuring out the type of a complex template (i.e., when using Spirit, et. al.). Lambdas and closures will simplify using the STL algorithms without having to create a lot of functors. REH
