      **Deprecated** Removes the record separator from the end of a string or an array of strings.

    For example `hello\n` becomes `hello`.
    Requires a single string or array as an input.

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

    @return [String] The converted String, if it was a String that was given
    @return [Array[String]] The converted Array, if it was a Array that was given
