Access reference objects in native function

[peter-jerry-ye]

Feature

I'd like to be able to access reference objects in native function with GC proposal (the apis in gc_export.h are great). Currently with signature (r) only if the type is between REF_TYPE_NULLREF and REF_TYPE_FUNCREF (btw I'm not sure if the comparison is correct ). It would be great if anything between REF_TYPE_HT_NULLABLE and REF_TYPE_NULLFUNCREF is supported.

Benefit

We can integrate better with gc proposal in terms of FFI (for example, no need to serialize/deserialize a structure just to modify a field

Implementation

I do not have a plan of implementation yet, and I'm not sure if it possible.

Alternatives

N.A.

@peter-jerry-ye yes, thanks for pointing out. Seems it should be type >= REF_TYPE_HT_NULLABLE && type <= REF_TYPE_FUNCREF.

Maybe it should be type >= REF_TYPE_HT_NULLABLE && type <= REF_TYPE_NULLFUNCREF?

OK, though the parameter type of native function is rarely set as (ref null? nofunc), (ref null? noextern) and (ref null? none). Please try #3317.

It solves the issue. Thank you.
