One nice feature of cargo that I wasn't previously aware of: you don't need to do anything after updating your Cargo.toml. In npm, you need to remember to `npm i` after changing package.json. It's not declarative and the state can get out of sync.

A pleasant surprise: updating the direct dependencies in difftastic has reduced the total transitive dependencies. I wasn't expecting that.

Smalltalk has a remarkable method named #become: that allows you to modify all pointers to a given object to point to a different object! https://gbracha.blogspot.com/2009/07/miracle-of-become.html This goes even further than updating instances when a class changes, it's changing instance references.
