This would annoy me:

[pbrannan@zaphod borg]$ ruby -w `which irb`
/usr/local/lib/ruby/1.6/irb/context.rb:129: warning: method redefined; discarding old irb_name
/usr/local/lib/ruby/1.6/irb/context.rb:200: warning: method redefined; discarding old math_mode=
/usr/local/lib/ruby/1.6/irb/context.rb:214: warning: method redefined; discarding old use_readline=
/usr/local/lib/ruby/1.6/irb/context.rb:201: warning: instance variable @math_mode not initialized
/usr/local/lib/ruby/1.6/irb/context.rb:171: warning: instance variable @use_tracer not initialized
irb(main):001:0> 

but perhaps having -w be default would convince the author to fix the
code that caused the warnings.
