[Development] Question about QCoreApplicationData::*_libpaths

[Иван Комиссаров]

Why? In case of QMap, we have no need to use operator= to change the map.
We simply detach and insert new data in it.
Of course, in case of multiple changes, the map can reach some "invalid
state" before changes are finished (i.e. in case we need transacted
changes, we have to use mutex anyway). But it is not neccessary in some
cases.
