The try/catch allows one to see that there appears to be a problem
inside Phobos, i.e. it determines that x.X is not the same type as x.X
and throws an assertion error. To handle this in the application is to
accept that Phobos is broken and not fixable. :-(

Unless this is actually just that x.X is not x.X even though it is x.X.
In this case it would be a module naming error in D and Phobos is not
wrong.
