Good point.

But strings are a bit tricky on the Arduino because the String class takes up too much memory and you're constantly having to do little workarounds that you wouldn't normally do on a full computer. The Arduino, when it runs out of memory, starts having random undefined behavior instead of showing a nice error message. I've had it happen a bunch of times already, so I'm trying to keep a rein on how much string processing I do in the Arduino code.
