Thank you for this, ikegami, it's what I was hoping to hear.

After spending most of the day yesterday learning about the process of how experimental features are implemented, discussed, life cycle etc, I'm confident that postderef is one that'll stay around.

I think I'll take one of my past modules where there are a lot of circumfix ops, and replace with postderef just to see if the overall readability is improved while scanning a file or not.
