The Dhall Configuration Language
I have been writing a fair amount of Dhall using autogenerated CloudFormation bindings ( https://github.com/jcouyang/dhall-aws-cloudformation/ ). It is a fantastic way to reduce boilerplate and factor out recurring blobs. My main frustration is that the type checker is not smart enough (or maybe the type system is undecidable?) - every time you want to use a polymorphic function, you must pass in the type parameters yourself (this is also true for empty lists and `None`). This makes simple FP idioms extremely noisy, to the point where you're better off writing longhand. In a language that's meant to be alleviating YAML/JSON boilerplate.
It's still a massive improvement, but it could be so much better if the typechecker was smarter.
