+## Any Position Method syntax

+Due to the hybrid nature of function call syntax
+and the left to right workflow in gwion,
+some syntaxic sugar is provided
+to call a function with arguments
+from both the left and right side
+
+Arguments coming from the left are referenced as `_`
+in the right hand side
+
+```gwion,editable
+fun void myfunc(int i, int j) {
+  <<< "${i} ${j}" >>>;
+}

+#! prints '1 2'
+1 => myfunc(_, 2);

+#! prints '1 2'
+2 => myfunc(1, _);
