Thank you for your thoughtful response. What I'm basically looking for is a short keyword to add to the top of a step or draw call just to keep things short. So something like
"""
live_load // or some other name, just an example.
/// Code proceeds here to be live reloaded
"""
Something like that would reduce the amount of effort to add livey-ness to any particular step, instead of trying to remember the 3 liner, or keeping it in your clipboard or whatever. I don't know if macros are necessary for this -- it sounds like you are onto something, perhaps this would be worthy of an opt-in preparser tag, eh? That would be le epic. Whatever you think makes most sense.
