What about "an implementation of this specification MUST achieve all the
whishes the humans ever had"; is that testable? ie., is there anybody
that is able to tell the requireemnt has been met?
More seriously, it is fairly easy to make a test assertion non-testable
as soon as you use an unqualified words such as 'all', subjective but
not targeted statements (ie, subjective statements where it is not said
who is supposed to make the statement), etc.

(I'm not saying that's it's easy to define what testable is - the
numerous threads on this topics that this mailing list has known show it
pretty well...)
