So I see many of you around here use

assembly. Is it just trollin' for /prog/, or do you actually perform your general-purpose programming in assembly? Is it really feasible to be a productive programmer by using just ASM?

You can use view patterns to get close to that

{-# LANGUAGE ViewPatterns #-}
import Data.Text (uncons)

f (uncons -> Nothing) = ...
f (uncons -> Just (x, xs)) = ...
