to_proc() public

Turns the symbol into a simple proc, which is especially useful for enumerations. Examples:

  # The same as people.collect { |p| p.name }
  people.collect(&:name)

  # The same as people.select { |p| p.manager? }.collect { |p| p.salary }
  people.select(&:manager?).collect(&:salary)
