The first example for Lambda 1.55 is: list<int> v(10); for_each(v.begin(), v.end(), _1 = 1); This is not useful at all. The first two question that every new user would ask are: - which header files do I have to include? - which namespaces are the things from? Is _1 the global that I already know from bind or not? A useful example would be: #include <list> #include <algorithm> #include <boost/lambda/core.hpp> int main() { std::list<int> v(10); std::for_each(v.begin(), v.end(), boost::lambda::_1 = 1); } I cannot even find the usual .cpp example files anywhere on http://www.boost.org/doc/libs/1_55_0/doc/html/lambda.html . I have been using Boost for a long time so I knew that Lambda headers would probably be in a directory called boost/lambda/. I also knew that list and for_each would most probably come from the standard library. But not everyone does! Material for beginners, especially "examples", should be compresensible. I do not understand why that is not the case for so many Boost libraries. Some libraries are telling you the namespace but not the headers: - DateTime - Function - Signals2 in the tutorials - Array (the only example is in the "Design Rationale") ... http://www.boost.org/doc/libs/1_55_0/doc/html/date_time/examples/general_usa... http://www.boost.org/doc/libs/1_55_0/doc/html/function/tutorial.html http://www.boost.org/doc/libs/1_55_0/doc/html/signals2/examples.html http://www.boost.org/doc/libs/1_55_0/doc/html/array/rationale.html Some libraries have better examples: - Atomic has useful examples with #includes and namespaces. - Random has very useful examples, too. - Unordered has minimal, but useful examples on the main page. ... http://www.boost.org/doc/libs/1_55_0/doc/html/atomic/usage_examples.html http://www.boost.org/doc/libs/1_55_0/doc/html/boost_random/tutorial.html#boo... http://www.boost.org/doc/libs/1_55_0/doc/html/unordered.html I am talking about the HTML documentation only. That's all for now.
