Okay, okay.  I understand your feeling.

|I would suggest that this feature request be extended to also introduce Array#keep_if.

The biggest reason (for me at least) was lack of counterpart of
delete_if, so if keep_if could gain consensus, I'd agree with adding
select! (and keep_if).  I was thinking of delete_unless, but was not
satisfied by the name.
