parser/state

    cfunction

    (parser/state parser &opt key)

    Returns a representation of the internal state of the parser. If a
    key is passed, only that information about the state is returned.
    Allowed keys are:

    * :delimiters - Each byte in the string represents a nested data
      structure. For example, if the parser state is '(["', then the
      parser is in the middle of parsing a string inside of square
      brackets inside parentheses. Can be used to augment a REPL prompt.

    * :frames - Each table in the array represents a 'frame' in the
      parser state. Frames contain information about the start of the
      expression being parsed as well as the type of that expression and
      some type-specific information.
