As currently promulgated in RFC 88, this would throw a Try::Except
exception with message 'MyFoo'.  If you want throw MyFoo->New(...)
you have to say so.

RFC 88 takes this approach so people writing simple scripts can keep
on saying throw "Can't open file $file." without having to get into
the details of exception objects at all.  Easy easy, hard possible.
