Sure, it is a matter of aliasing:

     $ irb
     irb(main):001:0> def require_with_puts(filename) puts filename;  
require_without_puts(filename); end
     => nil
     irb(main):002:0> alias require_without_puts require
     => nil
     irb(main):003:0> alias require require_with_puts
     => nil
     irb(main):004:0> require 'rubygems'
