You made me think of something similar but on a completely different context. Do we have a way to make IntelliJ autocomplete named parameters in method calls? The dueuno API has many such methods, like the “render” method in Grails. Named parameters are very convenient to extend the API with the downside of not being “discoverable” by the IDE. But they may be “described” to the IDE instead? I don't know I am randomly speaking but that would be useful to Grails as well (render, hibernate methods like save, delete, etc) Do you know if this is something that could exist in some reality?
