reflect
This is an experimental API. Given a class for a compiled Kotlin lambda or a function expression, returns a KFunction instance providing introspection capabilities for that lambda or function expression and its parameters. Not all features are currently supported, in particular KCallable.call and KCallable.callBy will fail at the moment.
