Brainbrain is a compiler language invented by User:TehZ, based on brainfuck. Every brainbrain-program is a brainfuck-program which takes the source to be compiled as input, and outputs the compiled source (as brainfuck (or brainbrain) code).
The simplest brainfuck compiler ever. (note that if this program is run using a brainfuck interpreter, it is a cat program)
- ℒ feels weirdly dual to this.
