           Summary: Static array .init is actually .init of the array
                    element type, not the array.

Let T be a type and n a size_t constant, then T[n].init is the same as T.init.

This causes the program code

---
    {
        int[5] x;

        if (x == x.init) { /* ... */ }
    }
---

to be rejected with the compiler error message "Error: incompatible types for
((x) == (0)): 'int[5u]' and 'int'", whereas

---
    static assert(x.init == x[0].init);
---

passes successfully.

Just executed this:

--------
void main()                       // 1
{                                 // 2
    int[5] x;                     // 3
                                  // 4
    if (x == x.init) { }          // 5 Code that should be legal
    if (x.init == x[0].init) { }  // 6 Code that is actually illegal
}                                 // 7
--------

And it produces:

--------
main.d(6): Error: incompatible types for (([0,0,0,0,0]) == (0)): 'int[5u]' and
'int'
--------

So it looks like the issue is fixed. Anybody know which pull fixed this, or
should I just close?

resilved/worksforme
