<p dir="ltr">You can still omit monads and keep pair of values in tuple and work with them easily, but I understand the point you are making.</p>
<p dir="ltr">But I should note that migration from PHP to Python also takes first impression of complication of many things, where instead of having "just index.php" with everything inlined you would have some wsgi protocols, wsgi servers etc, but later you understand that this was "the right thing". Same with Haskell, it does pay off a lot in future :)</p>
