Thanks for the feedback and sorry for the delayed response. I haven't filed a feature request yet but I did find a temporary fix. I was able to get similar functionality utilizing [partial functions in python](https://docs.python.org/3/library/functools.html#functools.partial). For example: ``` from functools import partial create_subscription(msg_type, ros_topic, partial(callback_function(), passed_variable)) ``` --- [Visit Topic](https://discourse.ros.org/t/callback-args-in-ros2/4727/3) or reply to this email to respond.
