Changes between Version 1 and Version 2 of Ticket #22400, comment 2

v1	v2
1	1	Having `$defaults` contain all valid parameters certainly helps a lot but I still think `extract()` is bad.
2	2
3		If I see `$foo` somewhere deep in the function, it's not immediately clear if this is a function-set value or a user-supplied value. Yes, I probably have to search either way to see where the variable comes from but by instead using `$args['foo']`, it's ~~more~~ clear that this is a configuration argument rather than just a data storage variable.

5	5	I think another question is what's the advantage to using `extract()`? I can't think of any other than saving keystrokes which shouldn't be a valid reason.
