Where is this needed?

Moved to parser.dart where it is used.

+  int parameterCount;
+  Function trampoline;
+  MethodTrampoline(this.parameterCount, this.trampoline);
+  Object invoke(target, List arguments) {
+    if (arguments.length != parameterCount) {
+      throw new IllegalArgumentException("${arguments.length} != $parameterCount");
+    }
+    switch (parameterCount) {
+      case 0:
+        return trampoline(target);
+      case 1:
+        return trampoline(target, arguments[0]);
+      case 2:
+        return trampoline(target, arguments[0], arguments[1]);
+      case 3:
+        return trampoline(target, arguments[0], arguments[1], arguments[2]);
+      case 4:
