+// You don't even need to write any code to test -- you can just test values and run that, even
+// though you wouldn't do that in real life :) `assert!` is a macro that needs an argument.
+// Depending on the value of the argument, `assert!` will do nothing (in which case the test will
+// pass) or `assert!` will panic (in which case the test will fail). So try giving different values
+// to `assert!` and see which ones compile, which ones pass, and which ones fail :)

+// values that are equal! Try giving it two arguments that are different! Try giving it two values
+// that are of different types! Try switching which argument comes first and which comes second!
