+      ACL2 is a logic and programming language in which you can model

+      properties of those models. "ACL2" denotes "A Computational
+      Logic for Applicative Common Lisp".
+
+      ACL2 is part of the Boyer-Moore family of provers, for which its
+      authors have received the 2005 ACM Software System Award.
+
+      NOTE: In nixpkgs, the community books that usually ship with
+      ACL2 have been removed because it is not currently possible to

+      Clojure is a dynamic programming language that targets the Java
+      Virtual Machine. It is designed to be a general-purpose language,
+      combining the approachability and interactive development of a
+      scripting language with an efficient and robust infrastructure for
+      multithreaded programming. Clojure is a compiled language - it
+      compiles directly to JVM bytecode, yet remains completely
+      dynamic. Every feature supported by Clojure is supported at
+      runtime. Clojure provides easy access to the Java frameworks, with
+      optional type hints and type inference, to ensure that calls to Java
+      can avoid reflection.
+
+      Clojure is a dialect of Lisp, and shares with Lisp the code-as-data
+      philosophy and a powerful macro system. Clojure is predominantly a
+      functional programming language, and features a rich set of immutable,
+      persistent data structures. When mutable state is needed, Clojure
+      offers a software transactional memory system and reactive Agent
+      system that ensure clean, correct, multithreaded designs.

+      PicoC is a very small C interpreter for scripting. It was originally
+      written as a script language for a UAV's on-board flight system. It's
+      also very suitable for other robotic, embedded and non-embedded
+      applications. The core C source code is around 3500 lines of code. It's
+      not intended to be a complete implementation of ISO C but it has all the
+      essentials. When compiled it only takes a few k of code space and is also
+      very sparing of data space. This means it can work well in small embedded
+      devices.

+      Python is a remarkably powerful dynamic programming language that
+      is used in a wide variety of application domains. Some of its key
+      distinguishing features include: clear, readable syntax; strong
+      introspection capabilities; intuitive object orientation; natural
+      expression of procedural code; full modularity, supporting
+      hierarchical packages; exception-based error handling; and very
+      high level dynamic data types.

+Subject: [PATCH] Bug 1143022 - Manually mmap on arm64 to ensure high 17 bits are clear. r=ehoogeveen
+
+There might be 48-bit VA on arm64 depending on kernel configuration.
+Manually mmap heap memory to align with the assumption made by JS engine.
