actually putting that in the section title -- and truthfully, maybe it
should be, for those who aren't deeply versed in PL but know enough
Lisp/Scheme to ask for this.

(fold (All (a b) ((a b -> b) b (Listof a) -> b))))
And got an error because (orig-module-stx) was #f. I'm not sure whether
it should have been or not, but I've fixed up this to handle that case
(having it just use the normal error message when that's #f, as I'm not
sure whether the error message would be correct otherwise).
However, it might just be that (orig-module-stx) should have not been
#f, in which case this should be checked out.
revision). So what we'll get here is the following:
Dotted + Dotted = Dotted (from the first case)
Dotted + x = x (since x refers to a free use of the dotted var)
x + Dotted = x (same)
I think this is correct.
instantiating dotted pre-types where the bound is _not_ free in the
pre-type base. I checked in a test case for this, that's something like:
(inst (plambda: (a ...) [ys : (Number ... a -> Number)] (apply + ys))
Integer Boolean String)
=
(Number Number Number -> Number)
These changes introduce no extra test failures, and we really have to
account for the bound here, and really even if the variable _does_
appear free within the pre-type base, it shouldn't be counted as a
"regular" variable outside of that scope.
Actually, maybe Dotted should behave like Constant, where it just
propogates until there's a separate free use that we're merging with,
in which case we just treat it like the free use (which will
eventually get fix-bound applied to it anyway). I think I'll make
that change next.
For example, we don't want the result type of the function to be free,
so it's more like:
G, D + {a}, S |- f : (t1 t2 -> t)
G, D, S |- t
(i.e. {a} not free in t)
Hmm.
