> I was actually in the school of thought that this article describes until I read and worked through the book How to Design Programs

What distinguishes the approach from what is presented in this blog post, can you provide a summary for those of us who haven't read the book? I am sincerely interested.

The book utilises a series of Scheme based teaching languages to teach about how to write functions for increasingly complicated data types. The language levels produce meaningful error messages for programmers of that particular level and goes on adding language features as you progress through the book.

The book furthermore teaches a design recipe which comes in handy when you are stuck with a problem. Basically it teaches you to write examples first so that you understand the problem instead of jumping onto the editor to write code first. The examples help you structure your data. The rest of the code follows from it.
