The only other thing I can think of that concerns me at all is if I'm trying to call a function that has been overloaded to take 1..N arguments using the preprocessor library or some other code generator. Then this code:
func(list_of<string>(), "foo", "bar", "baz");
might compile successfully and pass four arguments to func when I really meant to pass one argument:
func((list_of<string>(), "foo", "bar", "baz"));
I think was the motivation. I had a user that called a constructor: cons( list_of(3)(5), 4, 5 ); he wanted to pass 3 arguments, but only one was passed. I haven't tried it, but is adding parathesis enough to pass the three arguments forward?
This particular combination of advanced techniques seems unlikely enough that I would still rather have the comma operator. Given no other objections, I would vote to have list_of's comma operator reinstated.
Requiring paranthesis in certain contexts seems like a very subtle thing to do. I like easy syntax, but I also think surprising and subtle behavior can be a pain for users. -Thorsten
