/prog/ is moving slowly

so I will write fictional nonsensical Haskell code with nice Unicode

— Computes the anus of y
x :: Num a ⇒ a → a
x = λy·y×(y÷2)

— Charlie Brown
foo :: String → String
foo x = case lookup “x” x of
                 Just y → y
                 Nothing → x

The only good thing about coding in C or Sepples is that there's no particular reason to use a monospace font.
How is this specific to C or Sepples? Most languages can be written just fine with proportional fonts. Lisp and Objective-C are some of the rare exceptions, and even with them, the problem could be solved by a slightly smarter editor display formatter.
