Even cooler:

       proc{|*args| new(*args)}
     end
   end

   class Person
     def initialize(name)
       @name = name
     end

     def inspect
       @name.to_str
     end
   end

   %w(john bob jane hans).map(&Person) => [john, bob, jane, hans]

This could have been done just as well by modifying Enumerable#map in the core, without adding new syntax.

Where's the fun in that? :slight_smile:

I simply had to share my love with the wonderful #to_proc, which continues to amaze me with its flexibility.
