No, normal exceptions print just fine. e.g.

I'm wondering what's wrong the one I defined, the error message seems to
indicate that it doesn't have toString. It's wrong as there is one
derived from Exception.
Workaround was to use
alias toString = Base.toString;
Is this because "writeln" tries to use the one without parameters? If
you override one method, which as overloads, you need to override all
overloads or bring them into the same overload set with an alias, as
you've done above.
A base class and subclass have different overload sets [1].
