I would also like to add the argument about templates. Qt API is still
incompatible with STL in some places, so one cannot write a template
function that simply calls STL variant.
For example:
QString foo;
if (std::empty(foo)) // oops, fails to compile because QString misses
the .empty() method
Of course, in the user code we can just call .isEmpty()… but if we’re
writing a template function that accepts QString and std::vector, what
should we call?
Note that std::string misses .isEmpty() method, so there’s simply no
common subset that can be used. Ofc, one can check if .size() is 0,
but I guess more examples can be found (that’s the one I was annoyed
with).
So where is your patch to add this functionality?
