thanks for looking into this!
I'd be very happy if you updated the tutorial page with the current code. For each submitted change to a Wiki page, I receive an email with the diff that describes the change, so yes, there is (kind of) a review process built in.
Btw., there is no need to wait for any review feedback and no need to to worry about triggering too many emails, or making corrections multiply or later, I can easily deal with all that. In fact, I prefer several smaller changes over a single big one, especially when the smaller changes are "logically one unit each", where one logical unit is whatever you think is appropriate.
Feel free to make any changes as you desire!
Thanks in advance!
