Ah! Great, thanks - this is very close to what I was after. Anyone who's
as lazy as I am trying it might like to start with,
sqlt --parser DBI --dsn 'dbi:mysql:dbname=X;host=127.0.0.1' --db-user X --db-password X --producer 'ClassDBI' | perl -pe "s/use base 'DBI'/use base 'My::DBI'/; s/^DBI::/My::DBI::/"
...a hack to change the base class which isn't offered by sqlt (yet).
Note also that the producer somehow loses the DSN & auth.
Thanks also to Matt Trout and John Siracusa for extensive help with
their products off list; look forward to checking that out when I'm
back from holidays.
