Extending the use of `require'

Description

=begin
I was playing with Ruby tonight and thought up an interesting idea to make (({require})) a bit better, so you can load multiple files sequentially using one method call.

Currently, (({require})) supports one argument, and throws a (({TypeError})) if you pass an array:

irb(main):001:0> require %w(json yaml)
TypeError: can't convert Array into String

However, there's a way to patch Kernel that makes it respond to multiple objects passed in an (({Array})).

module Kernel
@@require = method :require

def require *args
args.flatten!
args.collect! do |a|
raise ArgumentError.new "arguments to `require' must be strings or symbols" unless a.is_a?(String) || a.is_a?(Symbol)
@@require.call a.to_s
end

 args.length == 1 ? args.first : args

end
end

The new behavior doesn't actually require the modification of any code that calls (({require})) (pretty much anything, really), and new code can take advantage of the new functionality instantly.

irb> require %w(json yaml)
=> [true, false]
irb> require :pp
=> false
irb> require 'rails'
=> true
irb> require %w(json yaml), :pp, 'rails'
=> [true, false, false, true]
=end

Thanks for considering this.
