This might come across as slightly trivial, but I enjoyed thinking about it none-the-less.

I've been thinking about the differences in modern programming syntax, and how we separate expressions.

Compile Time Polymorphism through meta-programming is a powerful way to express your ideas - learn about how to do this using C++

Run Time Polymorphism is a useful construct which allows us to change the behaviour of code depending on its input - but what are the costs associated with this technique?
