One interesting aspect of collecting coins in a platformer like mario: it makes the level stateful. You can see if you've been somewhere before based on whether there are coins present.

When writing long-lived programs (daemons etc) in Rust, I find myself asking *where* I should put data. In a GC'd language it's just "I have a string" but Rust forces me to find somewhere to put it. You do get a performance benefit for this work though.

Chekhov's repro: If a line of code is included in a bug report, it should contribute to the debugging somewhere.
