Good idea.

A very brief look into the DBI docs reveals:

  $dbh = DBI->connect($data_source, $username, $password)
            or die $DBI::errstr;
  $dbh = DBI->connect($data_source, $username, $password, \%attr)
            or die $DBI::errstr;
[...]
Examples of $data_source values are:

  dbi:DriverName:database_name
  dbi:DriverName:database_name@hostname:port
  dbi:DriverName:database=database_name;host=hostname;port=port
[...]
    For compatibility with old DBI scripts, the driver can be specified by
passing its name as the fourth argument to connect (instead of \%attr):

  $dbh = DBI->connect($data_source, $user, $pass, $driver);

    In this ``old-style'' form of connect, the $data_source should not start
with ``dbi:driver_name:''. (If it does, the embedded driver_name will be
ignored). Also note that in this older form of connect, the
$dbh->{AutoCommit} attribute is undefined, the $dbh->{PrintError} attribute
is off, and the old DBI_DBNAME environment variable is checked if DBI_DSN is
not defined. Beware that this ``old-style'' connect will be withdrawn in a
future version of DBI.
