Subtypes vs. Convertible Types
[------ The Types Forum ------- http://www.dcs.gla.ac.uk/~types ------]
My recent paper titled "Subtypes and Convertible Types" tries to answer
the following questions:
* What are subtypes after all?
* When should subtype rules be used?
* Are subclasses subtypes?
* Can we have more subclasses and hence more subtypes?
* Can we have more convertible types?
