A Haskell programmer and a Python programmer both programmed a CNC machine, and decided to blog about it. One of them talked about an object they milled and the modicum of glue needed to speak G-code, and the other described an elegant algebraic structure using rank-2 polymorphism to express milling paths on any arbitrary manifold embedded in R^3.

Which programmer was more likely to write which blog post?

This little joke is meant to paint a picture for how many programmers see (what they believe is usual) Haskell discourse—like that of the article—perhaps including the commenter you're responding to.
