Artful Code

newLisp does not have nested contexts. This is because contexts are not OO-style objects, although they can be used to prototype other contexts. In fact, contexts are name spaces that can be manually created as needed. However, since they create efficient hashes that can be used for many of the same purposes [...]

newLisp is a loosely-typed language. However, if you are developing a library or module that other projects may mix into their own code, it is useful to give helpful errors when a function receives incorrect input. Especially if your documentation is lax (which we know it never is), throwing usable errors when a [...]

The author states, “The first – and only – programming paradigm I was taught at college was OO.” Another recent blog post by a college CS tutor laments that object oriented design is the first (and often, the only) abstraction [...]

Paul Graham notes that, “A popular recipe for new programming languages in the past 20 years has been to take the C model of computing and add to it, piecemeal, parts taken from the Lisp model, like runtime typing and garbage collection.” This is what has made Python such a wonderful, elegant, and concise [...]
