Are there pronounceable names for common Haskell operators? [closed]
Solution 1:
Here is how I pronounce them:
>>= bind >> then *> then -> to a -> b: a to b <- bind (as it desugars to >>=) <$> (f)map <$ map-replace by 0 <$ f: "f map-replace by 0" <*> ap(ply) (as it is the same as Control.Monad.ap) $ (none, just as " " [whitespace]) . pipe to a . b: "b pipe-to a" !! index ! index / strict a ! b: "a index b", foo !x: foo strict x <|> or / alternative expr <|> term: "expr or term" ++ concat / plus / append [] empty list : cons :: of type / as f x :: Int: f x of type Int \ lambda @ as go ll@(l:ls): go ll as l cons ls ~ lazy go ~(a,b): go lazy pair a, b
Solution 2:
| sym | pronunciation |
|------|--------------------------------------------------|
| | | "such that" |
| <- | "is drawn from" |
| = | "is defined to be" / "is defined as" |
| :: | "has type" / "of type" / "is of type" |
| -> | "a function that takes ... and returns a ..." / |
| | "function that maps" / |
| | "is a function from" / |
| | "to" |
| $ | "apply" |
| _ | "whatever" |
| !! | "index" |
| ++ | "concat" |
| [] | "empty list" |
| : | "cons" |
| \ | "lambda" |
| => | "implies" / "then" |
| *> | "then" |
| <$> | "fmap" / "dollar cyclops" |
| <$ | "map-replace by" |
| <*> | "ap" / "star cyclops" |
| . | "pipe to" / "compose" / "dot" |
| <|> | "or" |
| @ | "as" |
| ~ | "lazy" |
| <=< | "left fish" |
Solution 3:
My personal favorites are "left fish" (<=<) and "right fish" (>=>). Which are just the left and right Kleisli composition of monads operators. Compose fishy, compose!
