I am testing with the latest pull from github and dmd ignoring "ref" when
passing array as ref argument. Kindly see the code below. When I run this code
it prints "Postblit called!" four time.

// 
struct Foo {
  this(this) {
    import std.stdio;
    writeln("Postblit called!");
  }
}

void barArray(ref Foo[4] _f) { /*do nothing*/ }

void main() {
  Foo [4] fooArray;
  barArray(fooArray);
}

Another testcase:
---
struct S
{
    int i;
    version(trigger_assert_in_main)
        // ` disable` will just be ignored
        // and postblit will not be called.
        // Looks like because of Issue 7579.
         disable this(this);
    else
        this(this) { assert(0); }
}

void f(ref S[3] arr)
{
    arr[0].i = 7;
}

void main() {
    S[3] arr;
    f(arr);
    assert(arr[0].i == 7);
}

This is definitely a bug, but is really *regression*?
I'd like to know the version of dmd which had worked correctly.

Ah, OK. I found the reason of this bug, and this is a regression of 2.060head
(Does not occurs in 2.059).
