Title: (h ||= {})[k]

Adding some failing specs (while I attempt to track this down):

```ruby
> Parser::CurrentRuby.parse('(h ||= {})[k]')
=> (send
(begin
(or-asgn
(lvasgn :h)
(hash))) :[]
(send nil :k))
```

```ruby
> ast = Parser::CurrentRuby.parse("(h ||= {})[k] = v")
=> (send
(begin
(or-asgn
(lvasgn :h)
(hash))) :[]=
(send nil :k)
(send nil :v))
```
