A list is a monad

I will die with the crushing embarrassment of not being able describe what a monad is, despite being a so-called (and apparently fake) programmer since the age of 10.

There's nothing embarrassing about not knowing the details of a sub-field you're not deeply involved in.

Like, why would you embarrassed about not understanding the details of MPLS networking if you're not a network engineer who works with MPLS?
