I expect this is an known issue but we may should fix this:
----
import std.stdio;

struct Foo {
    this(this) {
        writeln("Copy");
    }

    ~this() {
        writeln("DTor");
    }
}

void main() {
    Foo[] fs;
    fs ~= Foo();

    Foo[int] fas;
    fas[42] = Foo();

    // Even this doesn't change anything
    //destroy(fas);
    //destroy(fs);
}
----

You will never see "DTor". But if you work with ref count or C memory you would
hope and expect that your data is finalized. So, the compiler should finalize
the data if they is collected. Unfortunately I expect that we need a precise GC
for that? IMO the current behaviour is unexpected and bug prone.
As _workaround_ it would be helpful if destroy would work that way, but
currently it doesn't.

Somewhat of a duplicate of issue #9335.
