Results do not match other implementations

The following queries provide results that do not match those of other implementations of JSONPath
(compare https://cburgmer.github.io/json-path-comparison/):

• $[1:3]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["second", "third"]
  

  Actual output:

  ["second", "third", "forth"]
  

• $[:2]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["first", "second"]
  

  Error:

  JSON path parse error at position 1
  

• $[0:0]
  Input:

  ["first", "second"]
  

  Expected output:

  []
  

  Actual output:

  ["first"]
  

• $[0:3:2]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["first", "third"]
  

  Error:

• $..[0]
  Input:

  ["first", {"key": ["first nested", {"more": [{"nested": ["deepest", "second"]}, ["more", "values"]]}]}]
  

  Expected output (in any order as no consensus on ordering exists):

  ["deepest", "first nested", "first", "more", {"nested": ["deepest", "second"]}]
  

  Actual output:

  ["deepest", "first nested", "more", {"nested": ["deepest", "second"]}]
  

• $["key"]
  Input:

  {"key": "value"}
  

  Expected output:

  ["value"]

• $['']
  Input:

  {"": 42, "''": 123, "\"\"": 222}
  

  Expected output:

  [42]
  

  Error:

  JSON path parse error at position 1
  

• $[-1]
  Input:

  ["first", "second", "third"]
  

  Expected output:

  ["third"]
  

  Error:

  JSON path parse error at position 1
  

• $..key
  Input:

  {"object": {"key": "value", "array": [{"key": "something"}, {"key": {"key": "russian dolls"}}]}, "key": "top"}
  

  Expected output (in any order as no consensus on ordering exists):

  ["russian dolls", "something", "top", "value", {"key": "russian dolls"}]
  

  Actual output:

  ["russian dolls", "something", "value", {"key": "russian dolls"}]
  

• $.key-dash

  Input:

  {"a": "first", "2": "second", "b": "third"}
  

  Expected output:

  ["second"]
  

  Error:

  JSON path parse error at position 1
  

• $..*
  Input:

  {"key": "value", "another key": {"complex": "string", "primitives": [0, 1]}}
  

  Expected output (in any order as no consensus on ordering exists):

  ["string", "value", 0, 1, [0, 1], {"complex": "string", "primitives": [0, 1]}]
  

  Actual output:

  ["string", 0, 1, [0, 1]]
  

• $..*
  Input:

  [40, null, 42]
  

  Expected output (in any order as no consensus on ordering exists):

  [40, 42, null]
  

  Actual output:

  []
  

• $['key','another']
  Input:

  {"key": "value", "another": "entry"}
  

  Expected output:

  ["value", "entry"]

• $[ 0 , 1 ]
  Input:

  ["first", "second", "third"]
  

  Expected output:

  ["first", "second"]
  

  Error:

  JSON path parse error at position 1
