@Override
public ILogicalExpression visitScalarFunctionCallExpression(ScalarFunctionCallExpression expr, Void arg)
    throws AlgebricksException {
  ScalarFunctionCallExpression exprCopy = new ScalarFunctionCallExpression(expr.getFunctionInfo(),
      deepCopyExpressionReferenceList(expr.getArguments()));
  deepCopyAnnotations(expr, exprCopy);
  deepCopyOpaqueParameters(expr, exprCopy);
  copySourceLocation(expr, exprCopy);
  return exprCopy;
}

Function fn = (Function) fcExpr.getFunctionInfo();
