def /(*args)
  File.join(self.to_s, *args.map {|e| e.to_s})
end

#to_proc ⇒ Object

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)
