You are Reading the Name of this Esolang[1] is my favorite of the Brainfuck derivative esolangs. It consists of "0" and "1" characters which map to Brainfuck symbols via a Huffman encoding as well as brackets which wrap a subprogram which are reduced to "1" if the subprogram halts and "0" if the subprogram loops forever. This means that the problem of deciding whether a given string is a valid You are Reading the Name of this Esolang program is undecidable.
