It still has some performance issues that I say would make it hard to put into an industry environment. I think the teaching language part is in reference to Captain Teach, an IDE++ that the developers are using in the classes to support code review, automatic backups, and more. Pyret is being designed with the goal of encouraging good code, with tests being an integral part of every function, and clear differentiation between mutation and simple let bindings. I would teach this language just for those features, so my students would see how easy it is to get lost in spooky action at a distance, or in debugging the wrong portion of your code.
