"count" can possibly be complemented or replaced with occurrence as suggested.
It'd be nice to be able to denote last occurrence [-1].
And I suppose the indexing should be based on ordinary perl subscript indexing
- i.e. governed by the value of special variable $[
$field->delete_subfield( code => $code, # of course
occur => [0,2,3], # "occur" or "pos" or whatever...
match => qr/pat/, # doesn't need to be repeatable
);

I guess those work for me, as long as it's 'occurrence'. :-)
Or perhaps just 'occur'.
(If we allow -1, then I agree it should start at 0.)
