Which function are you referring to??

Yes, that would be pointless, but where does such a function appear in 
your code?

In your code, the & does two things:

1) It calls to_proc() on the specified object.  print() is a method of 
the Kernel module, and Kernel doesn't define to_proc().

2) It tells ruby to use the Proc object as a block.
