Bright is only one :o).

Oh, that's simple. A while ago people asked, how do I iterate a 
container (assuming the container is distinct from range). So I said, 
here's how I think:

Container!int c;
...
foreach (element; c.all)
{
    ...use element...
}

People said, that sucks! With opApply I don't need to append the .all 
thingie! So I told Walter to automatically call [] against the 
container. So people can now write:

foreach (element; c)
{
    ...use element...
}

All the container has to to is define opSlice() to return its "all" range.
