Yes, I do understand that declaring a variable to a user-defined type will
cause the program to crash on error.  I do believe that this would be useful
for debugging but not for production-quality programs.  I would expect types
to be unnecessary in my code before I called it production-quality!  But
types can also be used not for declaring a variable but as a special purpose
function for range testing.  And the program doesn't exit when type is used
in that fashion.
