## Last Week's Playground

This week I am going to present you the `with` expression in Pony. *The `with` expression???*, you ask?
Yes, this undocumented gem that definitely needs more coverage in the tutorial.

Here is the playground link: [https://playground.ponylang.io/?gist=3e3b043fa4ac8f6edea4f232776a3a52](https://playground.ponylang.io/?gist=3e3b043fa4ac8f6edea4f232776a3a52)

In case you want to submit one (which I highly recommend), just add it as a comment to the current [Last Week in Pony Issue](https://github.com/ponylang/ponylang.github.io/issues?q=is%3Aissue+is%3Aopen+label%3Alast-week-in-pony) and let people vote with `+1` reactions. The one with the most votes is presented (Or i just present them all. Depends on my Sunday evening mood).
