$.fn.filter() and $.fn.not() are needlessly asymmetrical

[maranomynet]

One automatically assumes $.fn.not() is simply an inversed $.fn.filter()

... which it isn't, as .not() doesn't accept functions as parameters, and .filter() doesn't accept elements, collections, or nodelists.

This asymmetry seems wholly needless and relatively easy to fix, and might even result in a more compact code.
