REBOL Language. The R Project for Statistical Computing. TXL Home Page. Ometa/ OMeta is a new object-oriented language for pattern matching.
It is based on a variant of Parsing Expression Grammars (PEGs) which we have extended to handle arbitrary data types. OMeta's general-purpose pattern matching facilities provide a natural and convenient way for programmers to implement tokenizers, parsers, visitors, and tree transformers, all of which can be extended in interesting ways using familiar object-oriented mechanisms. I am about to release a new version of OMeta/Squeak. Read all about it (and download the release candidate) here. Rust. Haskell. Racket. Ruby Programming Language. The Programming Language Lua.

The simplicity of Lua is a factor in this.
