Fixed

• #534 provides a fix for how it detects callable middleware. Previously, it relied on PHP's is_callable(), but that function can result in false positives when provided a 2-element array where the first element is an object, as the function does not verify that the second argument is a valid method of the first. We now implement additional verifications to prevent such false positives.
