Please say more about this language.  Did you have to declare the type 
of each of these Year overloadings?  Was the type always determinuted 
unambiguously by the use (e.g., calling a function using () vs. getting 
a property value)?

You could return an object value for Year that was callable and that has 
a default value.  See JSClass.convert for a starting point.  But beware 
that JS does not support overloading, so the results won't be seamless.
