I agree with you. And that is how it used to be, but then
some people didn't think that was convenient enough so now
we are stuck with a seq that (IMHO) stinks. :)
Having a seq that works on anything is occasionally very useful for
fixing space leaks, and the type class version was kind of ugly and
unwieldy. The type class pops up when you use ! in a data declaration,
which looks strange. But I agree that polymorphic seq does have some
painful side effects.
Polymorphic seq is not lambda definable, which I dislike.
