HolyC is very similar to regular C, so it's a very simple but powerful language. It was used to make all of TempleOS, so it definitely works to make programs.

Mussel is described as 'Interpreted programming language written in Rust. It was designed as a simple and flexible language with a focus on easy-to-read syntax and powerful expression evaluation. Mussel supports basic data types, variable bindings, functions, closures, control flow' and is a programming language in the development category. There are more than 50 alternatives to Mussel for a variety of platforms, including Linux, Mac, Windows, BSD and Self-Hosted apps. The best Mussel alternative is Python, which is both free and Open Source. Other great apps like Mussel are C (programming language), Rust, C++ and C#.

Wolfram Language is a symbolic language, deliberately designed with the breadth and unity needed to develop powerful programs quickly. By integrating high-level forms—like Image, GeoPolygon or Molecule—along with advanced superfunctions—such as ImageIdentify or...
Yon is an experimental, topos-oriented programming language: a compiled language whose semantics are drawn from category theory (elementary topoi, Heyting algebras, directed type theory) and whose runtime stores every value in a content-addressed heap built on the Leech lattice ?

Ada 2012 is the next generation of the world’s premier programming language for engineering safe, secure and reliable software.


Fortran (previously FORTRAN, derived from Formula Translating System) is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
Object Pascal is a multi-paradigm, object-oriented, component-based general purpose programming language.
Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level...
Pike is a dynamic programming language with a syntax similar to Java and C. It is simple to learn, does not require long compilation passes and has powerful built-in data types allowing simple and really fast data manipulation.

Beef is an open source performance-oriented compiled programming language which has been built hand-in-hand with its IDE environment.

Nelua is a systems programming language for performance sensitive applications, like real-time applications and game engines. Its syntax and semantics are similar to Lua, but its garbage collection is optional, it provides optional type notations, and it is free from an...
