Of course, one of the common knocks on Ruby is that naively referring to a function executes it, and to pass functions around avoiding

  list.map { |i| process i }

one must write

  list.map &method(:process)

or, as the Rails guys have done [1], open up Symbol#to_proc so that

  list.map &:process

works. This will be part of core Ruby in 1.9, but last I heard it's slow [2].
