+An invalid number of arguments was given when calling a closure.
+
+Erroneous code example:
+
+```compile_fail,E0057
+let f = |x| x * 3;
+let a = f();        // invalid, too few parameters
+let b = f(4);       // this works!
+let c = f(2, 3);    // invalid, too many parameters
+```
+
+When invoking closures or other implementations of the function traits `Fn`,
+`FnMut` or `FnOnce` using call notation, the number of parameters passed to the
+function must match its definition.
+
+A generic function must be treated similarly:
+
+```
+fn foo<F: Fn()>(f: F) {
+    f(); // this is valid, but f(3) would not work
+}
+```
