But that's kind of ugly too. I read it as qlsEmpty(), not qIsEmpty(). See what
I mean? On of those is a lower case L.
How about a new approach to adding free functions:
template<class T> bool isEmptyQt(const T &t) { return t.empty(); }

Subject: Re: [Development] QHash for Qt 6
That’s why in Qbs we have «stlutils» header [0]
I think, I already proposed in one of the similar Qt vs std threads an addition
of free functions to make life easier with std:: containers. As far as I
remember, Thiago’s main argument against using std::vector was that .empty()
looks ugly (and I completely agree with that!).
However, instead of adding
template<class T> bool qIsEmpty(const T &t) { return t.empty(); }
we keep discussing how ugly std is=)
PS: note, that there is std::empty [1] (which can be used with c-arrays as
well) in the standard library, so, again, Qt kind of misses feature parity here

It's funny because I have that issue each time I am forced to work with
somebody else's STL containers. :-) (Sometimes, <algorithms> can help, e.g.,
to find an element in an std::vector, but its arcane syntax with the pair of
iterators is a pain compared to just calling a method such as
QVector::contains.)
