What was the reason behind filter preserving the original array's keys? Is there a benefit to it? I'm most often filtering arrays where the key is an integer, so I'd expected filter to act more like it does in other languages creating a new array with values accessible by index.

I get that updating filter would lead to breaking changes, and there are probably times where the current implementation comes in handy, but it'd be useful to to have a function that filters an array and returns a new array that starts at zero.

If the maintainers feel like it would be useful and extend what phunctional is trying to do, I could work on an implementation.

I'd like to have a group_by function like this:

group_by(array('one', 'two', 'three'), 'strlen');
=> array(3 => array('one', 'two'), 5 => array('three'))

I'm available to implement it.
