It is convenient to have a trailing comma when defining an array - so as easy to add/remove code to add/remove an entry to the array array( 'key00' => 'value00', 'key01' => 'value01', 'key02' => 'value02', ... ) I suggest to PHP Development team to make it available in the syntax to have a leading comma array( ... , 'key00' => 'value00' , 'key01' => 'value01' , 'key02' => 'value02' ) in such way, we can thought of the leading commas as the list bulletings. And the same things would be lovely to be applied also to function parameter list. I don't see why not :) What do you thing about my suggestion? Hope to hear from you! -- Nam
