Even cooler:

class Class  
def to\_proc  
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? 🙂

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