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; });
The problem is that this allocates delegate, so it can't be used
in @nogc code.
What I want to do might lo

way to make it shorter, I don't know.

Would constructing the delegate by setting its .funcptr and
.ptr properties work in this case? You can have

Let's say I have two dub packages: A and B.
A is a library. B is library or application (does not matter) and
depends on A.
A has several configurations in dub.json.
How to build the B package that way it will use non-default
configuration of A?
