 Parameters can be added to an anonymous function by specifying the types as follows:
 ```
 addIntToString (int, String) => { a, b;
-  println(b + a)
+  print_line(b + a)
 }
 ```
 
 Named functions can have parameters **(with mandatory names)** like in this example:
 ```
 addIntToString(a: Int, b: String) => {
-  println(b + a)
+  print_line(b + a)
 }

 If a function does have parameters, you can call it with arguments in the right order; if the function is not anonymous, it's also possible to call it by using the names of the corresponding parameters:
 ```
 addNumbers(int a, int b, int c, int d) >> {
-  println(a + b + c + d)
+  print_line(a + b + c + d)
 }
 addNumbers(1, 2, 3, 4) # Call without names
 addNumbers(a = 1, b = 2, c = 3, d = 4) # Call with names
 addNumbers(1, c = 3, b = 2, d = 4)

 Types are *inferred*, which means that specifying types of variables or returned values is optional.
