There's no need for a special rule to bar the application of [] to the result of new, because it seems to me that the current rules already make such application ill-formed. That's because [] operates on a postfix-expression and "new (data*)" is not a postfix-expression. Is there's something I'm missing? Alberto --- [ comp.std.c++ is moderated.
