well i don't master XS to comment on that... but imagine if DBI instead
of returning an array of arrays on a query, returned an array of strings
which you would have to parse later to extract the info from each row ?
it wouldn't be nice ... :)

As for the second level API... it isn't finished yet... have only
implemented the functions i needed... but don't mind to share my current
version if anyone is interested.
