I see. I'd more likely have errors as first class, instead of a
DEFAULT function able to make the distinction. Anyway, it is
possible to discern the two cases with:
>> is-really-error?: func [code] [error? try compose [error? (code)]]
>> is-really-error? [first block]
>> is-really-error? [first block2]
I haven't tried it with any other case tough.
