That could work if subfields were objects, but they're just strings. It
could simply delete all of them unless a second parameter is passed in,
which would basically act like a filter:
$field->delete_subfield('a', qr/badsubject/);
That sounds pretty good, though I'm working with a database where I
found a 6xx field with two identical occurrences of subfield 2. So what
you propose would, I suppose, delete both of them and I'd have to put
one back in. Add another parameter to specify which occurrence?
