calling 'eldoc-message' directly.
+** The introduction of record types (see below) brings several
+incompatibilities:
+
+*** The return value of 'type-of' is no longer a reliable indicator
+for the type of an object. For example, a return value of 'integer'
+now means that the object in question is either an integer or a record
+named 'integer'. To reliably test the type of an object, use the
+predicate functions such as 'integerp'. Don't define record types
+whose names clash with primitive type names.
+
+*** The printed representation of a record named 'hash-table' now
+clashes with the printed representation of a hash table. Don't define
+record types named 'hash-table'.
