Let's say I want to map some range using some context.
The obvious way is to do:

uint[3] arr = [1,2,3];
uint context = 2;

auto r = arr[].map!(delegate(value) { return value * context; });

To me the obvious way is to use a lambda, not a delegate:

    uint[3] arr = [1,2,3];
    uint context = 2;
    auto r = arr[].map!(value => value * context);
