Malbolge: Intentionally difficult to reason about esoteric language

Interestingly since the last time I looked at this stuff (around 2015) it looks like there have been some new and interesting approaches to generating Malbolge programs, see the “Update” comments here: http://www.acooke.org/malbolge.htm

I first found Malbolge via the “discoverer” of the first hello world program, Andrew Cooke - he was at one point a prolific contributor to Quora, and at some point decided to disappear themselves from the community like a lot of early Quora power users.
