+#+end_src
+*** TODO update lexert
+*** TODO update ast
+*** TODO update parser
+** TODO implement partial function ...
+#+begin_src rlox
+cosa := make(Cosa, feld1: 42)
+function :: fn(self:Cosa, b: Number) -> Number
+res := function(cosa,44)
+#+end_src
+*** TODO ... to undericlty create method
+#+begin_src rlox
+res := cosa.function(44)
+#+end_src
+*** TODO ... to make pipeline
