You can always do something like this:

$ cat foo.rb
def foo; puts 'foo'; end
$ cat bar.rb
def bar; puts 'bar'; end
$ irb
irb(main):001:0> module Kernel
irb(main):002:1>   alias :require_orig :require
irb(main):003:1>   def require *args
irb(main):004:2>     args.each { |a| require_orig(a) }
irb(main):005:2>   end
irb(main):006:1> end
=> nil
irb(main):009:0> require 'foo', 'bar'
=> ["foo", "bar"]
irb(main):010:0> foo
foo
=> nil
irb(main):011:0> bar
bar
=> nil
