    1. Honestly, at this point, I don't even know what tools I'm using, and which is responsible for what feature. Diving into the code of capybara and cucumber yields hundreds of lines of metaprogramming magic that somehow accretes into a testing framework. It's really making me loathe TDD despite my previous youthful enthusiasm.

      opinion: too much metaprogramming magic

      I'm not so sure it's "too much" though... Any framework or large software project is going to feel that way to a newcomer looking at the code, due to the number of layers of abstractions, etc. that eventually were added/needed by the maintainers to make it maintainable, decoupled, etc.

    1. The modern sense of "an X about X" has given rise to concepts like "meta-cognition" (cognition about cognition), "meta-emotion" (emotion about emotion), "meta-discussion" (discussion about discussion), "meta-joke" (joke about jokes), and "metaprogramming" (writing programs that manipulate programs).
    1. The most widely used form of macros in Rust is declarative macros. These are also sometimes referred to as “macros by example,” “macro_rules! macros,” or just plain “macros.” At their core, declarative macros allow you to write something similar to a Rust match expression.
