      An interesting consequence of Scala 3's context functions is that since the parameter's name isn't chosen at the call site (it's implicit), it's often accessed using a helper method, and that method will have a consistent canonical name across codebases. That helps readability.

      Just found a good use case for context function at work, but I will have to do it with scala 2 syntax for a bit before pushing the team to upgrade to scala 3.

      Luckily you still have the { implicit foo => ... } syntax in Scala 2, so in theory, that part of your upgrade should be just a matter of removing the lambda variable.

      Indeed. But really excited about all the new toys coming with scala 3

      Yes, I wasn't suggesting for a moment that you should stick with Scala 2! ;)
