     * Replaces format elements in a string with the string representation of an
     * object matching the list of arguments specified. You can give as many
     * params as you need, or an array with values.
     *
     * ##Usage
     * Using numbers as placeholders (encloses between `{` and `}`), you can get
     * the matching string representation of each object given. Use `{0}` for
     * the fist object, `{1}` for the second, and so on.
     * Example:
     * `Text::format('{0} is {1} years old, and have {2} cats.', 'Bob', 65, 101);`
     * Returns: 'Bob is 65 years old, and have 101 cats.'
     *
     * You can also use an array to give objects values.
     * Example: `Text::Format('{0} is {1} years old.', ['Bob', 65, 101]);`
     * Returns: 'Bob is 65 years old, and have 101 cats.'
     *
     * If give an key => value array, each key stands for a placeholder variable
     * name to be replaced with value key. In this case, order of keys do not
     * matter.
     * Example:
     * `$arg0 = ['name' => 'Bob', 'n' => 101, 'age' => 65];`
     * `$format = '{name} is {age} years old, and have {n} cats.';`
     * `Text::Format($format, $arg0);`
     * Returns: 'Bob is 65 years old, and have 101 cats.'
     *
     * @param string               $format An string containing variable placeholders to be replaced.
     * @param string[]|array|mixed $args   Object(s) to be replaced into $format.
     *   placeholders.
     *
     * @return string
     * @throws InvalidArgumentException if $format is not an string or placeholder values are not string-convertibles.

     *   php.net/functions.arguments.html#functions.variable-arg-list.new
     * @todo   Implement formatting, like IFormatProvider or something like that.

Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.
