For completely other reasons, I came across "Range-based for

With that, the Qt best practice could become
for (const auto list = getQList(); const auto &v : list) {
...
}
Which may or may not be pretty, but avoids the extra line of code and
keeps the scope clean.
We could even wrap this in a macro for convenience. We would call that macro
'foreach' for example.
Ah no, wait, this name is already taken by a macro that does exactly that :-)
Jokes aside, I think we still should let users use Q_FOREACH for implicitly
shared containers.
