std.container.util

template make(T) if (is(T == struct) || is(T == class))

Returns an initialized object. This function is mainly for eliminating construction differences between structs and classes. It allows code to not worry about whether the type it's constructing is a struct or a class.

Examples:

auto arr = make!(Array!int)([4, 2, 3, 1]);
assert(equal(arr[], [4, 2, 3, 1]));

auto rbt = make!(RedBlackTree!(int, "a > b"))([4, 2, 3, 1]);
assert(equal(rbt[], [4, 3, 2, 1]));

alias makeList = make!(DList!int);
auto list = makeList([1, 7, 42]);
assert(equal(list[], [1, 7, 42]));
