To be fair, as much as Rust macros are nice, it is a losing battle to go up against the Lisp macro system. Lisp might have its flaws, but macros in Lisp are second to none.

When to use them is a whole different story. But examples of macros I like are `when` and `unless`. Yes, simple, but they show a nice example of their power.

For more complicated once, love it or hate it, but the `loop` macro is probably THE prime example of a powerful macro.
