Couldn't it be some less weird, just like the anonymous functions in JavaScript and Go? Even the lambda in Java is much readable than c++.

It give me the feeling that, c++ gives every corner a special syntax, or c++ adds new features by adding new syntaxes, there is no the word "reuse" in the process of improving c++.

In go, anonymous functions and general functions and methods have no much differences. But in c++, lambda and general functions and class methods are too different. Using class methods as callback in c++ is awful.

C++1x features make c++ code less readable, for fewer and fewer programmers know every syntax corners in c++.
