Feature #7121: Extending the use of `require'
https://bugs.ruby-lang.org/issues/7121

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.
