better_launch: a replacement for the ROS2 launch system - intuitive, simple, memorable

And when you do need flexibility, I think the flexibility people are usually looking for is to launch 50 instances of the same node for a swarm or something like that.

OpaqueFunction allows you to write arbitrary imperative Python code with whatever library imports you want. I’ve used it a lot for launch file flexibility. But I really do think that flexibility can be more of a detriment than a help for team projects.

FYI: I added ForEach/ForLoop actions to do exactly this. You can use it in XML/YAML, so there’s no need to use Python/OpaqueFunction for this (at least as of Kilted). See: Requesting feedback: new for-loop action for ROS 2 launch files to repeat entities - #5 by christophebedard.

(I don’t mean to derail the discussion, but I thought it was worth spreading the news about new relevant features.)
