module allowing subs to build and return objects on-the-fly

 Object::Result adds a new keyword to Perl: result
 .
 That keyword acts like a return, but instead of a list of values to return,
 it takes a single block which specifies the behaviour (i.e. the methods and
 operator overloading) of an object to be returned.
 .
 The intention is to make it much less onerous to return clean, properly
 encapsulated objects...instead of returning lists of values or references to
 arrays or hashes.
