haskell oneliner with programming ligatures

Some obfuscated code (not particularly typical) as found and explained on
<https://stackoverflow.com/questions/12659951/-obfuscated-haskell-code-work>
featuring multi-character combinations <$>, <*>, =<<, >>= substituted by
"modern" coding fonts such as <https://github.com/tonsky/FiraCode>.

This whole practice seems like an awful idea to me, but regardless needs to
be represented for font comparison.
