The function parameter to jQuery.grep should be optional

[Michael Mior]

It would be great if the team could consider making the function parameter to grep optional.

I would suggest that

$.grep(['a', 'b', false]);

be the equivalent of

$.grep(['a', 'b', false], function(x) { return x; });

to allow the removal of falsy values. Note that this wouldn't be a breaking change.

Here is a simple jsFiddle demonstrating the suggested behaviour: ​http://jsfiddle.net/NwRBe/

Since grep is mainly used internally, I don't think this will make it into core.
