Jsone 3.0.2 (2020-03-03)
========================

Bugfixes
--------

- ## Part fix for #168: Enforce all error messages match

  Made sure error messages for arithmetic operations, builtins, and strings are the same.

  Added error messages for array indexing. (#168)
- Fixed the issue of speacial values in '$let' not evaluating.

  Values like 'if-then-else' statements, '$eval', and rendered keys.
  The values evaluate to an object, the values of which are evaluated.
  For example, the operations below no longer return an error:

  title: let with a value of $if-then-else
  $let:
    $if: something == 3
    then: {a: 10, b: 10}
    else: {a: 20, b: 10}
  in:
    $eval: 'a + b'

  context: {'something': 3}
  result:  20

  -----

  title: let using values from the parent context
  $let:
    "b": {$eval: "a + 10"}
  in:
    $eval: 'a + b'

  context: {'a':5}
  result:  20

  -----

  title: let with a rendered key
  $let:
    "first_${name}": 1
    "second_${name}": 2
  in:
    {$eval: "first_prize + second_prize"}

  context: {'name': "prize"}
  result:  3 (#249)
