Re: How to hand in a closure variable

Now I want the closure (aka delegate) to have a closure variable:

int a = 7;
int delegate(int) dg = { value => return value + a + 3; };
auto result = dg(123);

Unhappily, the code above doesn't compile. Tried various things, looked for samples on the D hompepage and in the book by Çehreli, but had no luck.

Some hints appreciated.
Thanks, Bienlein

auto dg = (int value) { return value + a + 3; };

or short-hand form:

auto dg = (int value) => value + a + 3;
