Subject: [ruby-talk:16327] Removal of a list of entries from an array

Hello,

Is there functionality equivalent to the following in Ruby?

	class Array

		def remove(list)
			dup.remove!(list)
		end

		def remove_r(list)
			dup.remove_r!(list)
		end

		def remove!(list)
			list.each {|n| if n = index(n) then delete_at(n) end }
			self
		end

		def remove_r!(list)
			list.each {|n| if n = rindex(n) then delete_at(n) end }
			self
		end

	end

Or am I the only one who is using this type of functionality a lot?
