Скачать или смотреть (ASMR-ish) A Bitter Old Man's Guide to Haskell: Monads

This video, the third entry of VARIK VALEFOR's _A Bitter Old Man's Guide to Haskell_, discusses Haskell's monads. Although a focus is placed onto the IO monad, most functions which are discussed within this video [apply] to all monads.
Specifically, the following functions are discussed:
-Bind
-KLEISLI composition operator
-Bind without passing value
-return
-filterM
-mapM
-mapM_
-forever

Vim is used as the text editor, and GHC is used as the compiler.
