Correction: Haskell jargon. The continued conflation of Haskell and functional programming as a whole annoys me greatly. (The majority of functional programming is not statically typed! Clojure and the other lisps are far more widely used than Haskell and the MLs, not even to mention that basically every language has first-class functions now.)

"Constant" is a term almost never spoken at Haskell circles, and "referential transparency" appears much more often within lispers and Clojure practitioners than between haskellers.

It is a stretch to suggest that Haskellers don't discuss referential transparency as much as Lispers do. It's a fundamentally important concept in writing and reasoning about Haskell programs.

There's a large "fish don't talk about the water" effect. When talking about Haskell, people talk about referential transparency, but when writing Haskell, it's very rare.
