  Instead of style, you can also specify character for true value.

• in => any

  Input stream (e.g. array or filehandle).

• notion => str (default: "perl")

  What notion to use to determine true/false.

  perl uses Perl notion.

  n1 (for lack of better name) is just like Perl notion, but empty array and empty hash is considered false.

  TODO: add Ruby, Python, PHP, JavaScript, etc notion.

• out => any

  Output stream (e.g. array or filehandle).

• style => str (default: "one_zero")

  Available styles:

  • Y_N: N Y

  • check (uses Unicode): ✓

  • check_cross (uses Unicode): ✕ ✓

  • dot (uses Unicode): ●

  • dot_cross (uses Unicode): ✘ ●

  • heavycheckcross (uses Unicode): ✘ ✔

  • one_zero: 0 1

  • t_f: f t

  • true_false: false true

  • v_X: X v

  • y_n: n y

  • yes_no: no yes

• true_char => str

  Instead of style, you can also specify character for true value.

Return value:

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
