Subject: Suggestion: Hash.remove

Something I often find useful is a version of Hash.delete which returns the 
hash rather than the deleted item. Useful for terse chained code.

class Hash
  def remove!(*some_keys)
    some_keys.each { |key| delete(key) }
    return self
  end
  def remove(*some_keys)
    return dup.remove!(*some_keys)
  end
end


Perhaps something like it is already planned for the next version? If not, 
perhaps the Hash maintainer might consider something like it.
