> C++'s std:: tools are more useful than the bespoke tools in libtransmission's C code. Nearly every time I go in to fix or change something in libtransmission, I find myself missing some C++ tool that I've come to take for granted when working in other code, either to avoid reinventing the wheel (e.g. using std::partial_sort() instead of tr_quickfindFirstK(), or std::vector instead of tr_ptrArray) or the better typechecking (e.g. std::stort() instead of qsort()).

I think it's more to glib development entering an ice age, than a language issue.

Glib had an impressive roadmap list around 8-10 years ago, copying much of STL features, but of course nothing much materialised after GNOME 3 caused an exodus of GTK developers.
