How to read code: the next generation
Reading type signatures will become the part of basic computer literacy curriculum taught in elementary schools.
While they taught you how Microsoft spreadsheets operated kids in future will learn some lambda calculus instead.
Types will be the standard user interfacing element to access computer systems. It will replace the buttons and text boxes of the present day and ordinary people will use them every day.
This article tells what these "types" are and gives a taste of how to read type signatures. Then I explain why I think this is useful and conclude with an example of reading code with types. I assume that you understand a bit of basic algebra.
