ditto.

I updated the comment, the old code violates the language.  Florian and I
discusses this initiailization when I was working on default values for function
parameters.

Oh, OK. So the final Function FN = ... was accidental. Nevermind thenm thanks
for fixing it!

-  // The existence of this final triggers b/5078969.
-  static final Function FN = () { return 42; };
 
-  Other1() { }
+  // Static variables must be initialized with compile time constants.
+
+  static Function FN;
+
+  Other1() {
+
+    if (FN == null) {
+      FN = () { return 42; };
+    }
+  }
   void newMethod() { }
 }
