jemfinch suggested that the author did not understand the phrase, but it was not obvious to me that jemfinch understood it--a "cargo cult" and "cargo cult science/mathematics" are two different concepts, and I find physics literacy on HN rather low.
By "appropriate," I meant to suggest the author's usage of it can be construed as consistent with Feynman's meaning. I linked the source so folks could decide for themselves if the author's claim was correct in addition to having a meaning we could all agree on.
[I don't know anything about Haskell, I was just trying (and apparently failing) to clarify some muddy discourse.]
To people who had read the essay and were familiar with the post-Feynman epithet "cargo cult X" it will have been plain that jemfinch knew what it meant and that the original author was clueless about how to apply it.
