Re: Remove Value node struct

Agree to the motive and +1 for the concept.

+1 Looks like so, it can be simply removed.

0001 looks fine to me.

0002:
  there's an "integer Value node" in gram.y: 7776.

-            n = makeFloatConst(v->val.str, location);
+            n = (Node *) makeFloatConst(castNode(Float, v)->val, location);

makeFloatConst is Node* so the cast doesn't seem needed. The same can
be said for Int and String Consts.  This looks like a confustion with
makeInteger and friends.

+    else if (IsA(obj, Integer))
+        _outInteger(str, (Integer *) obj);
+    else if (IsA(obj, Float))
+        _outFloat(str, (Float *) obj);

I felt that the type enames are a bit confusing as they might be too
generic, or too close with the corresponding binary types.


-    Node       *arg;            /* a (Value *) or a (TypeName *) */
+    Node       *arg;

Mmm. It's a bit pity that we lose the generic name for the value nodes.

regards.
