You mean partial _application_. The author called FORTH a concatenative language, and FORTH definitely doesn't have partial application. In fact, FORTH doesn't even have a type system. Perhaps this is a miscategorization?

fngi does have a type system which modifies a stack. However, it will be lacking many high-level type system features, being similar (but smaller and lighter-weight) than golang. Not totally sure if it qualifies or not.
