Cannot use complex expressions like hash['foo'] += 1 with hyper-spec

[catmando]

This is due to an issue in the current unparser gem: mbj/unparser#117

You may get an error like this when running a spec:

(string):1:20: error: unexpected token tOP_ASGN
(string):1: hash.[]("foo") += 1
(string):1: 

The problem is the unparser incorrectly generates hash.[]("foo") += 1 instead of hash['foo'] += 1.

The good news its pretty easy to find such expressions and replace them with something like

hash["foo"] = hash["foo"] + 1

You need to pass the modern AST format to unparser.

works with parser 3.0 and all settings on per mbj's comment.
