This is not really a new post, but merely a convenient place to gather my old posts on type systems and how they might improve Scheme. The 5 parts are:
Part 1: My first misguided type system
Part 2: A critique of type systems
Part 3: A second critique of type systems
Part 3.5: The criterions for a good type system
Part 4: My second proposal for a Scheme type system
I am sorry that I haven’t been working on Scheme much lately, but I have been busy with philosophy.
