+Only a single explicit lifetime bound is permitted on trait objects.
+
+Example of erroneous code:
+
+```compile_fail
+trait Foo {}
+
+type T<'a, 'b> = dyn Foo + 'a + 'b; // error: Trait object `arg` has two
+                                    //        lifetime bound, 'a and 'b.
+```
+
+Here `T` is a trait object with two explicit lifetime bounds, 'a and 'b.
+
+To fix this error, consider removing one of the lifetime bounds:
+
+```
+trait Foo {}
+
+type T<'a> = dyn Foo + 'a;
+```
