Lean 4 is both a programming language and an interactive theorem prover, designed to support formal reasoning while also functioning as an efficient and extensible general-purpose language. The project serves researchers, mathematicians, programmers, and formal methods users who need a system for writing machine-checked proofs as well as executable programs in the same environment. One of its defining characteristics is its emphasis on extensibility, since Lean 4 is built to allow users to develop custom automation, metaprogramming tools, and domain-specific extensions instead of being limited to a fixed proving workflow. ...

Zero is an experimental programming language from Vercel Labs designed with AI agents as first-class users. The project explores what a language, tooling system, and standard library might look like if agents need to read, debug, repair, and ship code reliably. It focuses on a small and regular language surface, structured diagnostics, predictable tooling, and machine-readable outputs. Zero is still pre-1 and intentionally unstable, so its syntax and APIs are meant for exploration rather than production use. ...

mruby is a lightweight implementation of the Ruby programming language designed for embedding and integration into applications, particularly in resource-constrained environments such as embedded systems or game engines. It maintains compatibility with modern Ruby syntax while offering a significantly reduced footprint compared to the standard Ruby interpreter. The system includes its own virtual machine, bytecode compiler, and interactive shell, enabling developers to write, compile, and execute Ruby code efficiently. One of its core strengths is its embeddability, allowing developers to integrate scripting capabilities directly into applications written in C or C++. mruby also includes a package system called mrbgems, which enables modular extension of functionality through additional libraries. ...

Externum is one language for three targets: - readable Python-style code with real, enforced type declarations - inline Bash for system control (`cmd` and %% bash blocks %%) - compiles to a standalone .exbc bytecode artifact — runs without source The compiler is written in Externum itself (minimal Python bootstrap). - struct / enum / trait / impl (Rust-flavored), match-case, defer - $"…" string interpolation, pipeline operator x |> f(a, b) - compiles to Python, to real Bash (set -euo pipefail) and to the EXBC VM - TUI IDE, REPL, browser playground, built-in DRM/licensing stack - NEW in 4.3: externum translate — import existing Python (AST) and Rust code 400+ unit/integration/differential tests in CI. ...

... * Enable programming-by-contract and other high-level features (as long as they incur no extraordinary costs at run-time). * Provide a stricter and more platform-independent type system than C. * Allow direct use of existing C and platform (e.g. Win32 API) libraries. This phrase from the "SPL Language Reference" says it all: "One could say SPL is what C should have been, were it not for the limitations of the time when C was designed".
