I'm not contesting that (at this time). What I meant is that allowing a range
to seek beyond its bounds looks counter nature to me. If it was called a stream
it wouldn't be so bad. It's mostly a naming thing.
For instance, let's say I have a file with this content:
[0,1,2,3,4,5,6,7,8,9];
I call popFront 5 times, so the content of the range conceptually becomes this:
[5,6,7,8,9];
Then I call a function, say seek(2), to return to the third element. Does this
add back elements in my range?
[2,3,4,5,6,7,8,9]
Adding back elements to a range seems quite un-range-like to me. Seeking to a
position relative to the first element in the "container" (the file) would be
even more so.
Now call it a stream and it looks more natural to do these operations. But
perhaps it's only me.
