c++ - Why doesn't Qt's qHash() have an overload for std::shared_ptr? -

-

i found out, surprise, following code not compile out of box in c++14 using qt 5.4:

qset<std::shared_ptr<sometype>> var;

the problem there no overload of qhash() method std::shared_ptr, or other smart pointer far can see: http://doc.qt.io/qt-5/qhash.html#related-non-members

it seems natural me have following overload (or similar):

template <typename t> uint qhash(const std::shared_ptr<t>& ptr, uint seed = 0) {     return qhash(ptr.get(), seed); }

but not exist. cannot qt developers overlooked. need include special header? reason why not exist?

speak of devil, , doth appear: https://codereview.qt-project.org/113340

this cannot qt developers overlooked.

it's not overlook, it's qt doesn't have endless resources add qhash overloads stl type has operator==.
