+ * the conditions where it happens should be clearly described,
+ * and they should be detectable and predictable,
+ * so the programmer using the function can avoid triggering the error.
+ *
+ * Such descriptions often uses words like
+ * "must" or "must not" to describe the condition,
+ * and if you see words like that in a function's documentation,
+ * then not satisfying the requirement
+ * is very likely to cause an error to be thrown.
+ *
+ * Example (from [String.contains]):
+ *
+ *        `startIndex` must not be negative or greater than `length`.
+ *
+ * In this case, an error will be thrown if `startIndex` is negative
+ * or too large.
+ *
+ * If the conditions are not detectable before calling a function,
+ * the called function should not throw an `Error`.
+ * It may still throw a value,
+ * but the caller will have to catch the thrown value,
+ * effectively making it an alternative result rather than an error.
+ * The thrown object can choose to implement [Exception]
+ * to document that it represents an exceptional, but not erroneous, occurrence,
+ * but it has no other effect than documentation.
+ *
+ * All non-`null` values can be thrown in Dart.
+ * Objects extending `Error` are handled specially:
+ * The first time they are thrown,
+ * the stack trace at the throw point is recorded
+ * and stored in the error object.
+ * It can be retrieved using the [stackTrace] getter.
+ * Errors that merely implement `Error`, and doesn't extend it,
+ * will not store the stack trace automatically.
+ *
+ * Error objects are also used for system wide failures
+ * like stack overflow or an out-of-memory situation.
+ *
+ * Since errors are not created to be caught,
+ * there is no need for subclasses to distinguish the errors.
+ * Instead subclasses have been created in order to make groups
+ * of related errors easy to create with consistent error messages.
+ * For example, the [String.contains] method will use a [RangeError]
+ * if its `startIndex` isn't in the range `0..length`,
+ * which is easily created by `new RangeError.range(startIndex, 0, length)`.
