- Lightness: Orion source code fits under 3k SLOC and its binary is under 2MB.
- Portable: Orion code is run on a virtual machine, that avoids architecture-specific problems.
- Purely functional: Pattern matching, immutability, side effects control.
- Elegant: It embeds shorthands such as
'<expr>for(\ () <expr>),[x y z]for(Cons x (Cons y (Cons z Nil)))or{ <expr>* }for(begin <expr>*).
You will need: the Rust toolchain (1.50+), a "make" program, a POSIX shell (linked in /bin/sh) and Git.
