Can you explain, in an issue on GH, what doesn't currently work that you would like to work? I suspect this would be problematic to solve because of connection management. Right now, if Executable isn't implemented for a given type, the assumption is that get-datasource can be called on it, and then DataSource is Executable and knows how to get a connection and close it when it is done.

execute-batch! is a special case because it works with a PreparedStatement and assumes that if you pass it something other than a Connection, it can call get-connection and close that when it is done -- but it has to use runtime type checking to do that and that is a performance hit that other functions must not have.

I will do that. Thank you
