As a side note : While there are a few corner cases where this is hardly 
avoidable (and yet I'd rather test on interface, not on concrete type), 
this kind of cose is exactly what OO polymorphic dispatch is supposed to 
avoid (no, don't tell me: I know you can't easily add methods to most 
builtin types).
