CASL extra function "packRules" never throws when the received value is not expected

[balboFK]

Describe the bug
If you try to use CASL extra function packRules with an primitive that is not expected like: [{}] it never throws and consumes all you CPU, might get into a infinite loop or something but it never throws or finishes.

To Reproduce

1. Just instantiate the CASL extra and call packRules with an object array like : [{}]

Expected behavior
Should throw or finish executing since the data is not workable for the packRules function

Interactive example (optional, but highly desirable)

Good catch. It will never throw. It relies on typescript types to receive proper arguments shape.

But I agree that it shouldn’t run infinitely. I’ll fix that

Nice! I'll wait for it, thanks for the reply!

fixed in @casl/ability@6.3.3
