+## Style #12.2

+Constraints:

+- For each 'thing' class, let's bring the `info` methods from the Things style (#11)
+
+- In the Things style, we used inheritance via a Python call to `super` to call a shared function from a base class
+
+- We should apply this concept of code-reuse, but make sure to do so without using inheritance
+
+- In typed languages, using delegates (or `Callable` in Python) is a recommended solution
+
+Note:
+
+A [delegate](https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/delegates/using-delegates?source=recommendations) is a type that safely encapsulates a method, similar to a function pointer in C and C++. Unlike C function pointers, delegates are object-oriented, type safe, and secure
