    This is either in a category theory book or was written by someone who is going to fucking hate category theory

      Looks like a category theory book. And they’re right: using A to notate the identity arrow is ridiculous.

      Found it! It’s from pg. 3 of An Introduction to Category Theory (2011) by Harold Simmons.
