Last Week in Pony - September 24, 2023
Items of Note
Pony Development Sync
Audio from the September 19th, 2023 sync is available.
We kept a tight 20 minutes on this week’s sync. Bang bang bang. Not a lot that would be of interest to the casual listening public, but, it’s only 20 minutes, so heck. Give it a listen.
We have an open Zoom meeting every Friday for the community to get together and well, do whatever they want. In theory, Sean T. Allen “owns” the meeting and will often set an agenda. Anyone is welcome to show up and participate. Got a Pony related problem you need help solving and prefer to do it synchronously? Give Office Hours a try.
There were no Office Hours this week while Sean was out on vacation.
If you’d be interested in attending an Office Hours in the future, you should join some time, there’s a calendar you can subscribe to to stay up-to-date with the schedule. We do our best to keep the calendar up-to-date.
Community Resource Highlight

There are many community resources that can go unappreciated until just the right time when someone hops into the Ponylang Zulip asking a question or facing a problem we have all had at one time or another.

Looking at this page, we can see that constraints are applied to the type parameters. The most permissive combination is
class Foo[A: Any #any] which is
Any type with
#any reference capability; this is also the default combination when both are left out so is equivalent to writing
