Dynamic schemas are supported, same as in KS 0.2x.  Supplying a document with
an unknown field still triggers an exception, so you just have to iterate over
all fields in the unknown document and call spec_field() for anything which
hasn't been seen before.

    while (my $doc = get_next_doc_from_somewhere()) {
        for my $field (keys %$doc) {
            next if $schema->fetch_type($field);
            $schema->spec_field(name => $field, type => $type);
