Why dynamic allocation for Option objects?

[Kevin Regan]

I'm wondering why you do this:

connection->set_option(new mysqlpp::FoundRowsOption(true));

rather than something like this:

connection->set_option(mysqlpp::FoundRowsOption(true));

or

mysqlpp::FoundRowsOption opt(true);
connection->set_option(opt);

Sincerely,
Kevin Regan
