It seems like `std.algorithm.each` is not executed in the example
below.
Could anyone tell why?
Thank you.
import std.algorithm;
void main(string[] args) {
int[] arr = [1, 2, 3, 4, 5];
arr.each!((ref e) => {
writeln(e); // does not print
++e;

ref2491's original code is valid, but doesn't have the intended meaning.
`e => {foo(e);}` is the same as `(e) {return () {foo(e);};}`, i.e. a
(unary) function that returns a (nullary) delegate. Calling it

in a multiline statement, i believe you must use :
arr.each!((ref e) {
writeln(e);
++e;
})
"=>" is for oneliner
though i don"t understand why it fails silently ??
