Having to support legacy systems with 15y+ development where the system works but you wish you didn’t have to spend so much effort figuring out types?

Or maybe you are an expert with a framework, you are very productive with it, you know the tricks, but you wish it had types support so maintaining these systems would be easier.

Picking a “better” language or learning a framework in another language is not always a pragmatic choice.
