Hah.. good catch! Thanks for the tip :-) Here's the new results:
With to_proc shorthand: real 0m1.449s user 0m1.335s sys 0m0.033s Without to_proc shorthand: real 0m0.376s user 0m0.347s sys 0m0.016s Also ran it on 1.9.1. Seems to run exactly the same speed both ways. With to_proc shorthand: real 0m0.204s user 0m0.172s sys 0m0.014s Without to_proc shorthand: real 0m0.201s user 0m0.180s sys 0m0.013s I do sorta prefer the shorthand to_proc syntax. I'll probably start using it more often since the performance difference on it isn't too bad anymore, and looks to become increasingly irrelevant as Ruby 1.9 and 2.0 come out.
