Ayaz Hafiz	710a10a29c	Check for invalid cycles after type solving recursive defs ... Disallow cycles that pass through a non-function value. Since we evaluate eagerly, having one such cycle means there is at least one path in the program that (likely) has unbounded recursion. Of course we can't be certain (halting problem), but it's very likely, and avoids stuff like #1926. Also, mono (as it's done today) won't work if things in a cycle aren't functions.
