When I was learning Haskell, I had a coding dream with a twist.

In that dream, I wrote small programs, compiled and executed them. The twist was that the result of the execution was presented to me in the form of physical constructs, composed of square hollow section pipes welded together.

I would then walk around the structure, examine it, and wonder, why a particular part of the structure is welded to the whole structure diagonally, instead of a 90-degree angle. Must be a bug somewhere.
