Those new examples work nicely. I'll have to remember the word "turbofish" :-)

Nah, I think we're at a good stopping point. I'll post the num traits topic on users, and the operator coherence one on internals, so maybe you will jump in there. I'm generally pretty private online, so I wouldn't take you up on the offer to continue in email. However, you've been really helpful and patient, and I sincerely appreciate it. Thank you again.
