Since I do more PHP than anything else at the moment, I would be so confused. => is used for totally different things, see snip below:
$var = array(
'first' => 1,
'second' => 2,
'third' => 3,
);
When I started programming there was languages that accepted them in any order and that just made me confused. If I would have been forced to the correct order directly mabe it would have been easier now.
