EDIT: The API was used to find this, so the json returned is (in this case) :
{'parseError': 'Parse error 1:12: (line 1, column 12):\nunexpected " "\nBad 
symbol', 'version': '4.2.26'}

Thanks for the report, it somehow missed my notifications. I'll take a look at 
this in the context of Hoogle 5 (hosted at http://hoogle.haskell.org/) at some 
point.

There is now no concept of a parse error, so this ticket is redundant.

Is there? 

https://www.haskell.org/hoogle/?mode=json&hoogle=%5Ba%5D+-%3E+%28a+-+%3E+m+%5Bb%
5D%29+-%3E+m+%5Bb%5D

still results in 

{"parseError":"Parse error 1:12: (line 1, column 12):\nunexpected \" \"\nBad 
symbol","version":"4.2.26"}

Has a new version not been deployed yet?

The new one is at hoogle.haskell.org, and doesn't have any concept of parse 
errors, but also doesn't have a JSON API yet. I'm using 
https://github.com/ndmitchell/hoogle/issues/74 to track adding the JSON API.
