OK. I am with you now.

Is

opt->type != SANE_TYPE_STRING && opt->size
             > (SANE_Int) sizeof (SANE_Word)

the only way for the frontend to tell that an array is expected?

I'm wondering about the best way to handle this in Perl, which doesn't
have sizeof().

I'm thinking that adding opt->max_vals might be best, as defining
something like SANE_Word_sizeof just feels hackish.
