Just tried the following program:
...
#lang typed-scheme
(require/typed
srfi/1
(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.

we either end up doing the traversal wholesale or throwing some of that

get rid of this useless remove, since it's just going to overwrite it

This makes the change mentioned in the log message for r10735 (the previous
...
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.

I'm not sure if this is correct, but this handles the cases where we're
...
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.

Actually, I want to be careful with this.
...
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.

There's no reason we can't allow foldl on a rest arg, as long as the types
...
match up appropriately. Let's do it!

We have to be careful here -- for example, one of the test cases was failing
...
because the last thing in the instantiate was a function type, which is
a cons. Look for a cons whose cdr is an identifier.
