I'm trying to do something simple like creating an array of
struct S from a float array via map:
---
void main()
{
float[] vals = [1.1, 2.1, 3.1, 4.1];
import std.algorithm: map;
auto arr = vals.map!`S(a)`.array;
writeln(arr);
}
struct S(T)
{
T t;
}

If I instead do ie. map!`cast(int)a` it works fine.

Generally don't use casts, unless you know what you are doing
(and often you don't).

struct Foo(T) {
T t;
}
void main() {
import std.stdio, std.algorithm,
Another synonym is list.

As for guarantees for class destructors - you have hard
guarantees that if memory is reclaimed, destructor was called
before. But no guarantees memory will actually be reclaimed.
There is an issue with structs that are directly allocated on
heap - destructors are never called for those. You will want to
change those into classes for GC to do at least something about
it.
