    /**
     * 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:
     *
     * ```php
     * $format = '{0} is {1} years old, and have {2} cats.';
     * echo Text::format($format, 'Bob', 65, 101); // 'Bob is 65 years old, and have 101 cats.'
     * ```
     *
     * You can also use an array to give objects values:
     *
     * ```php
     * $format = '{0} is {1} years old, and have {2} cats.';
     * $data   = ['Bob', 65, 101];
     * echo Text::format($format, $data); // 'Bob is 65 years old, and have 101 cats.'
     * ```
     *
     * This is specially useful to be able to use non-numeric placeholders (named placeholders):
     *
     * ```php
     * $format = '{name} is {age} years old, and have {n} cats.';
     * $data = ['name' => 'Bob', 'n' => 101, 'age' => 65];
     * echo Text::format($format, $data); // 'Bob is 65 years old, and have 101 cats.'
     * ```
     *
     * For numeric placeholders, yo can convert the array into a list of arguments.
     *
     * ```php
     * $format = '{0} is {1} years old, and have {2} cats.';
     * $data   = ['Bob', 65, 101];
     * echo Text::format($format, ...$data); // 'Bob is 65 years old, and have 101 cats.'
     * ```
     *
     * > Note: If objects are not convertible to string, it will throws and catchable exception
     * (`InvalidArgumentException`).
     *
     * @param string      $format An string containing variable placeholders to be replaced. If you provide name
     *   placeholders, you must pass the target array as
     * @param array<int, mixed> $args   Object(s) to be replaced into $format placeholders.
     *   You can provide one item only of type array for named placeholders replacement. For numeric placeholders, you
     *   can still pass the array or convert it into arguments by using the '...' syntax instead.
     *
     * @return string
     * @throws InvalidArgumentException if $format is not an string or placeholder values are not string-convertibles.
     * @todo   Implement formatting, like IFormatProvider or something like that.
