Just did my own little test...

~$ irb -rbenchmark -rubygems -ractive_support
>> class Fixnum; def timestwo; self * 2; end; end
=> nil
>> puts Benchmark.measure { (1..10000000).map { |n| n.timestwo } }
 13.570000   0.100000  13.670000 ( 13.795564)
=> nil
>> puts Benchmark.measure { (1..10000000).map(&:timestwo) }
 48.370000   0.080000  48.450000 ( 48.517666)
=> nil

Yikes
