+#### Note: this error code is no longer emitted by the compiler.
+
+You gave too few lifetime arguments. Example:
+
+```compile_fail,E0107
+fn foo<'a: 'b, 'b: 'a>() {}
+
+fn main() {
+    foo::<'static>(); // error: wrong number of lifetime arguments:
+                      //        expected 2, found 1
+}
+```
+
+Please check you give the right number of lifetime arguments. Example:
+
+```
+fn foo<'a: 'b, 'b: 'a>() {}
+
+fn main() {
+    foo::<'static, 'static>();
+}
+```
