It's true that you can already do something similar -- although not as easily.
I personally always use this pattern:
function stuff($required1, $required2, $options = array()) {
extract($options);
}
This still, however, makes everyone who call my functions have to do a lot of
extra typing:
stuff(1, 2, array('a' => 'b')) // well, not a lot but they have to type array(
) EVERY TIME
instead, wouldn't it be nice if
a) Every function ever written could become extensible
b) People would be able to use that really easily: stuff(1, 2, 'a' => 'b', $c
=> $d)?
PS: Please let's NOT make it stuff(1, 2, a => 'b', c => $d) as it would take
away the option of having variable key names, which we can have in array().
Also it would create slight ambiguity with constants.
