Hmmm, very good point.

The issue seems similar (at least in spirit) to that of implicit 
casting. Implicit casting is, in a sense, syntactic sugar, saving 
you from writing "cast(mytype) myval" all over the place. It's 
also a highly contentious issue; everyone seems to be have their 
opinion of the extent to which implicit casting is a good thing.
