It seems the latest change breaks another query:

• $[*].bar[*].baz
  Input:

  [{"bar": [{"baz": "hello"}]}]
  

  Expected output:

  ["hello"]
  

  Actual output:

  [["hello"]]
  

If you are interested, you can use the json-path-comparison as a regression suite, all current queries are mapped with current and expected results in https://github.com/cburgmer/json-path-comparison/blob/master/regression_suite/Golang_github.com-bhmj-jsonslice.yaml.
