I wonder if it is better to pass MonoClass *klass to check_for_invalid_array_type, since line 6298 will always be executed. That way we could save one function call.

So the problem is that if you start with a MonoType and then call mono_class_from_mono_type_internal it is not an exact roundtrip. In particular you lose the MonoType:byref bit. Because a MonoClass is not able to represent a byref type. (This is kind of an annoying limitation in Mono but fixing it is probably a ton of work).
I thought about instead returning the klass from check_for_invalid_array_type, but it's kind of a weird incidental return value. In any case mono_class_from_mono_type_internal is pretty quick to call since it's just a switch on a value (MonoType:type) that we already looked at.

Gotcha! My original thought was to returning the klass from check_for_invalid_array_type. But since it is not costly, I am okay with current implementation.
