+/**
+ * Check whether the given object is any subtype of Message or is a specific
+ * Message by passing the type.
+ *
+ * Just like `instanceof`, `isMessage` narrows the type. The advantage of
+ * `isMessage` is that it compares identity by the message type name, not by
+ * class identity. This makes it robust against the dual package hazard and
+ * similar situations, where the same message is duplicated.
+ *
+ * This function is _mostly_ equivalent to the `instanceof` operator. For
+ * example, `isMessage(foo, MyMessage)` is the same as `foo instanceof MyMessage`,
+ * and `isMessage(foo)` is the same as `foo instanceof Message`. In most cases,
+ * `isMessage` should be preferred over `instanceof`.
+ *
+ * However, due to the fact that `isMessage` does not use class identity, there
+ * are subtle differences between this function and `instanceof`. Notably,
+ * calling `isMessage` on an explicit type of Message will return false.
