I'm in need of a way to create a local array that isn't GC'ed. It must
be dynamic in the sense of setting the size at compile time but it will
be used only in scope and only on structs.

function x(int y)
{
    bool[y] arr;

    arr ~= 3;

}

I care about slicing or anything but appending, removal, and indexing. I
don't even need bounds checking. I don't see a need to get locked in to
the GC for such simple cases.

One way is to make x() a function template:

import std.stdio;

void x(int y)() {
   bool[y] arr;
   arr[y/2] = true;
   writeln(arr);
}

void main() {
    x!5();
}
