This program gives a confusing error message. Does anyone know why the xs
in the body doesn't have type (List Foo)?
The error message is much better if the return type is (Listof Integer).
It only complains about Foo being unbound instead of Foo unbound and got
a listof error.

It's because the type `Foo` is not defined, so it cannot have a sensible
representation. Erroneous types like this
I think we should at least make `(Listof Error)` turn into `Error`.
That would eliminate the error message than Ben reported.

It's because the type `Foo` is not defined, so
4 matches
