That works in C++, unless you mark that constructor with

What do you mean by out-out?

Do we know the reason why it is not supported?
Basically implicit construction was considered a mistake in C++
and D didn't want to repeat that mistake. Most code

Something like this:
test([1,2,3]);
This is the "implicit construction" I sometimes talk about
and D doesn't support it, by design (alas).
I have a custom Buf struct (working as a simple vector)
struct Buf(T) {
size_t cap, len;
T *data;
@nogc
this(T[] arr) {
reserve(arr.length);
foreach(item; arr) {
push(item);
}
}
...
};
And I have a function like this:
void
