Thank you for the kind words! Zaki did allude to work on speed: Of note are several speed improvements.

• The shortcutting will be due to expanding what was already there, now referred to in the Ufunc code (following R.S. Bird's naming of it) as "left zeroes" (in commit https://github.com/PDLPorters/pdl/commit/58df094ff320183bc983227f0854982fc3c5e782).
• The speeding up of the full scan is slightly mysterious, and I'd be highly interested if you could do a git bisect to see which change caused that?

The "add loop" stuff is only relevant for those who write PP code, but it does make doing so much, much nicer.

If you'd like to help in heralding in city squares, you will be most welcome! If you'd like to participate in the community and you're not already doing so, then please join either or both of the IRC channel and the mailing lists.
