a programming language that had a built-in support for a simple form of literate programming
Software documentation Respected computer scientist Donald Knuth has noted that documentation can be a very difficult afterthought process and has advocated literate programming, written at the same time and location as the source code and extracted by automatic means. The programming languages Haskell and CoffeeScript have built-in support for a simple form of literate programming, but this support is not widely used.
Polyglot persistence In 2006, Neal Ford coined the term "polyglot programming", to express the idea that applications should be written in a mix of languages to take advantage of the fact that different languages are suitable for tackling different problems. Complex applications combine different types of problems, so picking the right language for each job may be more productive than trying to fit all aspects into a single language. This same concept can be applied to databases; so that you can have an application that talks to different databases using each for what they are best at to achieve an end goal, thus giving birth to polyglot persistence.
