Writing a reasonable program in Brainfuck isn't that hard. Malborge, on the other hand, was specifically designed to be impossible to write useful programs in.

Writing a reasonable program in Brainfuck isn't that hard. Malborge, on the other hand, was specifically designed to be impossible to write useful programs in. IIRC, Brainfuck was designed to be easy to write a compiler for. From the wikipedia article linked above: "Malbolge was so difficult to understand when it arrived that it took two years for the first Malbolge program to appear. The first Malbolge program was not written by a human being, it was generated by a beam search algorithm designed by Andrew Cooke and implemented in Lisp"... "A correct 99 Bottles of Beer program, which deals with non-trivial loops and conditions, was not announced for seven years".
