Czy istnieją wymowne nazwy dla zwykłych operatorów Haskell? [zamknięte]

Czytam Naucz się Haskell dla wielkiego dobra, i nigdy nie wiem, jak wymówić operatory Haskella. Czy mają "prawdziwe" nazwiska? ?

Na przykład, jak można odczytać na głos wyrażenie takie jak to?

Just (+3) <*> Just 9

Wiem, że >>= to "bind", ale co z innymi? Ponieważ Google nie bierze pod uwagę znaków niealfanumerycznych, trudno jest przeprowadzić skuteczne wyszukiwanie...

Zdaję sobie sprawę, że można tworzyć własne operatory, więc oczywiście nie wszystkie operatory mogą mieć nazwy, ale spodziewam się, że te wspólne (np. te zdefiniowane w Applicative lub Monad) muszą mieć nazwy...

Oto jak je wymawiam:

>>=     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

Moje Ulubione to "lewa ryba" ( I "right fish" (>=>). Które są tylko lewą i prawą kompozycją Kleisli operatorów monad. Skomponuj fishy, skomponuj!
