Herb Sutter on Lambdas

Why care about C++0x lambda functions? Syntactically, they are nothing but sugar for function objects. However, they are an essential and enabling sugar that will change the way we will write C++ code more often than most people realize.

This talk from last PDC covers what lambda functions are and how to use them effectively, including how lambdas touch many wide-ranging kinds of code — from their convenience when writing concurrent and scalably parallel code, to how they stand to revolutionize STL usability and programming, to how they enable such small conveniences as local functions and local variable initialization.

Note that lambda functions, although futuristic, are not a far-future feature. They are available today in several shipping C++ compilers, including Intel C++ 11, Microsoft Visual Studio 2010, and gcc 4.5. The future is now. Come find out how this powerful feature affects you and your code.

Herb Sutter is the chair of the ISO C++ committee. He is responsible for the design of lambda functions in Visual C++ 2010 and their integration in the Parallel Patterns Library. He is partly responsible for the design of lambda functions in the C++0x standard, notably capture defaults and final syntax.

  • Hi Diego,

    Linking some existing videos is nice, producing some new videos would be better ;)

  • Producing new articles (or at least videos with transcripts) would be even better. :D

  • Thanks for your feedback, @Mark and @Bob!

    We are certainly making new stuff that we'll be publishing through 2011 covering several areas. We'll still highlight recent content not mentioned in the blog, though. As long as we have an interesting combination of both. Some people just don't look for info but trust on our RSS feed to get the essentials.

    By the way, I'm to make a public call for content. We have a lot to share but we feel, after reading comments in this blog and other channels, that there's a lot of talented people out there. More to come soon.

  • why did it take so long to come up with c++0x. i think that the designers of c++ didn't know what they were doing
