Maybe we should add
empty_list_of<int>()
? It's quite trivial to add.
Does list_of<T>() have a default value for its T parameter?
No, how could it?
... as it cannot assume what T will be.
In that case, I'm confused about why list_of<int>() inserts a default value.
It was a consistency issue. Consider list_of<int>()(42); // 0, 42 list_of<int>(42)(); // 42, 0 list_of(42)(); // 42, 0 would you expect that to be any different? -Thorsten
