Can we split this into two methods for FunctionExpression and
FunctionDeclaration.

Do we even need a Local for a FunctionExpression?

Added a TODO, for discussion with Johnni.

     assert(node is ir.FunctionDeclaration || node is ir.FunctionExpression,
         failedAt(currentMember, 'Invalid local function node: $node'));
-    return _map.putIfAbsent(node, () {
+    var lookupName = node;
+    if (node is ir.FunctionDeclaration) lookupName = node.variable;
+    return _map.putIfAbsent(lookupName, () {
       String name;
       if (node is ir.FunctionDeclaration) {
         name = node.variable.name;
       } else if (node is ir.FunctionExpression) {
         name = '';
       }
       return new JLocal(name, currentMember);
     });
