Most implementations offer extensions, but are otherwise backwards compatible, of course, the compiler that comes with Racket can also run in R5RS or R6RS mode. Caddr is too low level. The cons function actually accepts any two values, not just a list for the second argument. The most obvious one is making cons construct an immutable pair (mcons constructs a mutable pair). It has native support for design by contract. It also contains a structure system that is a bit cleaner than the R6RS record system. Using Scheme libraries in a Racket program. Is it possible for planetary rings to be perpendicular (or near perpendicular) to the planet's orbit around the host star?

Scheme was invented largely to create an academically rigorous, “principled” Lisp, built from the ground up from a minimal core, which could be extended in Scheme itself. In a few cases Racket has constructs whose behaviour deviates from R5RS. In this article, I will compare racket vs. racquet. Using macros to properly decompose a problem domain teaches new developers good habits, improving composibility and reliability when tackling large programs. Scheme syntax is extremely regular and easy to pick up. What is the best programming language to learn first? It also offers, for example, hash tables (and recently sets were added). Your second example is yielding #f because the system is creating a new floating point number for each argument; they're not the same object. Could all participants of the recent Capitol invasion be charged over the death of Officer Brian D. Sicknick?

Additionally, since Scheme syntax is extremely flexible, it can easily be re-purposed for teaching non-deterministic and logic programming. Although syntax is different from that of mainstream languages, S-expressions are a perfect match to functional programming. Racket also includes a lot of standard libraries (e.g. There is no need to learn a new language like Prolog when the same ideas can easily be expressed with Scheme syntax. Get app's compatibilty matrix from Play Store. Racket goes further than most Scheme implementations in providing built-in data structures. I think using a different name is a wise decision: using the same name for different languages that have a common origin is IMO confusing.

If you want an especially quick introduction to Features in Racket not implementable by macros alone: The module and macro system are much more general than the RnRS specification. I personally make Lisp programming mostly in Common Lisp and I miss in much cases the lack of pattern matching implementation. Podcast 302: Programming in PowerPoint can teach you a few things. This, in turn, severely limits uses of whatever-learned-with-Scheme, for real-world use. Racket (noun) A broad wooden shoe or patten for a man or horse, to allow walking on marshy or soft ground.
