Glad to hear the article did what I meant for it to do :)
replyAnd yes, another comment mentioned that Scala supports this syntax!
Clojure CL as well have macros that let you thread results from call to call, but you could argue that's cheating because of how flexible Lisp syntax is.
replyClojure also has the anonymous function syntax with #(foo a b %) where you essentially get exactly this hole functionality (but with % instead of $). Additionally there’s partial that does partial application, so you could also do (partial foo a b).
replySomeone else in the comments mentioned that scala does this with _ as the placeholder.
