Not sure where I read this but found it while reading about software architecture. It kinda stuck with me. Any other resources which helps gain more understanding on this approach and implementing it. Any products out there which does this better.
HN and Viaweb come to mind. But even those were made by creating a product in parallel with the framework.
If you like this kind of thing, though, you might like to read On Lisp. There’s a free pdf copy floating around the internet.
