--- Comment #1 from Simen Kjaeraas <simen.kjaras at gmail.com> ---
This would perhaps more correctly be filed as 'int does not have opCmp'. Since
int does support the <, <=, >=, > operators it kinda, sorta has opCmp, but no
member by that name. That's not really an option for Typedef, as it's not a
magic type like int. At the same time, we absolutely expect MyInt.init <
MyInt.init to compile.

There may be a good argument for adding opCmp and friends to built-in types to
make generic code more generic, but removing them from Typedef is no solution.
