- Modules with a parameter without a default value will be automatically deferred until the hierarchy pass - Allows for parameters without defaults as module items, rather than just int the `parameter_port_list`, despite being forbidden in the LRM - Check for parameters without defaults that haven't been overriden - Add location info to parameter/localparam declarations
