constexpr auto kwk::for_each ( Func &&  f, C0 &&  c0, Cs &&...  cs  )

constexpr

Simple walkthrough over all elements of a container.

Applies the given function object f to every elements of a given kwk::container. Elements are iterated in order of the optimal memory access.

Parameters

f	Function object, to be applied to an element of c. The signature of the function should be equivalent to the following: void f(T&& v); with T convertible to the container's value_type.
c	A kwk::container on which elements f will be applied.

Returns

The function object f which could have been modified.
