> I guess the reason here is obvious, that llint_op_get_by_id doesn't know all the tricks that tryCacheGetByID knows.  I assume this is just not implemented yet, though do let me know if you are against more cleverness there (perhaps due to icache concerns).

This is bizarre.  Most of the tricks for polymorphism in the old interpreter are disabled (like proto, list, or chain accesses).

I agree that this is worth looking into.
