Hello,
A question regarding delegates and local variables:
I have the following code, which seems to indicate the delegate function
can access "b", but makes a private copy of it, instead of using the
"real" b.

Map is a lazy range.

import std.stdio;
import std.algorithm;
void main(){
int[] a = [1,1,1];
int b = 42;
auto c = map! ( delegate(x) { ++b; return x+b ; } )(a);
writeln("a = ",a);
writeln("b = ",b);
writeln("c = ",c);
writeln("b = ",b);
}

a = [1, 1, 1]
b = 42
c = [44, 45, 46]
b = 45
