Forth: Building a Brainfuck DSL in Forth using code generation - "[T]his article isn’t about writing a Brainfuck interpreter. I want my Brainfuck code to itself be valid Forth code, able to be embedded straight into a Forth program. This article is about writing a Brainfuck DSL. ... Not only is embedding a Brainfuck in Forth totally possible with Forth’s meta-programming facilities, it’s actually easier than doing it the regular way. In fact, our DSL won’t even model the code or code pointer of the Brainfuck machine. It doesn’t need to, the code is already in the interpreter."
