+Connection information arrayref.  Can either be the same arguments
+one would pass to DBI->connect, or a code-reference which returns
+a connected database handle.  In either case, there is an optional
+final element in the arrayref, which can hold a hashref of
+connection-specific Storage::DBI options.  These include
+C<on_connect_do>, and the sql_maker options C<limit_dialect>,
+C<quote_char>, and C<name_sep>.  Examples:
+
+  ->connect_info([ 'dbi:SQLite:./foo.db' ]);
+  ->connect_info(sub { DBI->connect(...) });
+  ->connect_info([ 'dbi:Pg:dbname=foo',
