for example i have an array
int[] a = [1,2,3,4,5];
and a function
auto twice = function (int x) => x * 2;
how can i apply the function to each element in a without using a
forloop? - is there a function to do this?
a.foreach(x => x * 2);
a == [2,4,6,8,10]
ddos:
auto twice = function (int x) => x * 2;
"function" is not necessary. And generally it's better to assign
to immutables, unless you need to mutate the variable "twice"
later.

thx alot! its not important to me that the function is not
evaluated in place
since you gave me such a straight answer i'd like to bother you
with another question :)
for example i have now two ranges:
immutable a = [1,2,3,4];
immutable b = [2,3,4,5];
how do i add the elements in a and b elem
ddos:
how do i add the elements in a and b elementwise
Several ways to do it:
void main() {
import std.range, std.algorithm, std.array;
immutable a = [1, 2, 3, 4];
immutable b = [2, 3, 4, 5];
int[] c1;
c1.reserve(a.length); // Optional.
foreach (immutable x, immutabl
