Status update:

Right now this is causing the following 2 bugs:

1. Currently, the below incorrect line of code:

```
int arr[2] = 1;
```

is being incorrectly treated the same as

```
int arr[2](1);
```

2. The following below correct line of code:
```
int arr[2] = static_cast<int[2]>(1);
```

fails with the error:

```
test-static-cast.cc:1:12: error: static_cast from 'int' to 'int[2]' is not allowed
int a[2] = static_cast<int[2]>(1);
           ^~~~~~~~~~~~~~~~~~~~~~
1 error generated.
```
