 // NOTE: This exercise did not originally include the function below.
-// But a change after Zig 0.10.0 added the source file name to the
-// type. "Narcissus" became "065_builtins2.Narcissus".
+// After Zig 0.10.0, `@typeName` began prefixing the returned type name
+// with the source file name. For example, "Narcissus" became
+// "065_builtins2.Narcissus".
 //
 // To fix this, we've added this function to strip the filename from
 // the front of the type name. (It returns a slice of the type name
-// starting at the index + 1 of character ".")
+// starting just after the ".")
 //
 // We'll be seeing @typeName again in Exercise 070. For now, you can
 // see that it takes a Type and returns a u8 "string".
