The implicit sharing of Qt containers is a nice trait that enables you
to write more

I don't know why André decided to ask about Qt containers, since they already
do support 64-bit sizes.
We write science data processing software
(github.com/bluequartzsoftware/dream3d) and there have been more than a few
times where we load up past 32 bit signed int number of elements in an array.
We are adding out-of-core to our software now which means we are definitely
going past signed 32

On one hand, I could say anyone that needs it once in a while could
simply use a std container.
On the other hand, for the "container of bytes"

Hi all.
In order to base my potential arguments in a certain discussion on a
neighboring list not purely just on my own experience with both Qt and
(independently) large data (a.k.a. "gut feeling") I would appreciate
if /you/ could help me to find a - very rough, readily admitted in
