    @summary
      **Deprecated** Returns a new string with the last character removed.

    If the string ends with `\r\n`, both characters are removed. Applying
    chop to an empty string returns an empty string. If you wish to merely
    remove record separators then you should use the `chomp` function.
    Requires a string or array of strings as input.

    > *Note:* **Deprecated** from Puppet 6.0.0, this function has been replaced with a
    built-in [`chop`](https://puppet.com/docs/puppet/latest/function.html#chop) function.

    @return [String] The given String, sans the last character.
