Just to implement the previous suggestion correctly(tm) this time.

This is more or less what I want
class Array;def reject!(&blk)
select(&blk).each{|e|delete e};end
def select!(&blk)
reject(&blk).each{|e|delete e};end;end

now if I do array.reject! I actually get array mutated
but it returns the non-rejected.
So kinda destructive/mutating select.
