void func(){ auto lambda = [](){}; decltype(lambda) other; } To fix the error, remove the need for the default constructor to be called. If the lambda doesn't capture anything, then it can be cast to a function pointer. Lambdas with a deleted assignment operator The following code...

C++ 编译器现在实现了带有许多新功能的 C++14 标准,如,变量模板、非静态数据成员初始化器、扩展的 constexpr 规范器、大小的取消分配函数、通用 lambda、变量长度数组、数字分隔器等。 改进了对 C 语言标准 C11 的支持:ISO C11 原子、通用选择和线程本地存储现已提供。 新的__auto_...
launches a parallel kernel which executes the provided GPU lambda function as the body of a parallel loop. When compiled for the CPU, the lambda is executed as the body of a sequential CPU loop. This makes parallel functions nearly as easy to write as a for loop, as the following code ...
You can define and call a recursive function in a single line with Y-combinator, e.g.: return (lambda y,x:y(y,x))(lambda f,x:1 if x==0 else x*f(f,x-1),5) But the walrus operator syntax is much more concise: return (f:=lambda x:1 if x==0 else x*f(x-1))(5) ...
