Quote of the Week
If C is like playing with knives and C++ is like juggling chainsaws then Rust is like parkour wearing protective gear while suspended from strings. It may look ridiculous at times, but you can do all sorts of awesome moves that would be damn scary or outright impossible without it.
Thanks to Christopher Durham for the suggestion!
