GLib also provides macros that use autocleanup.[0]

Using a bunch of macro magic, they allow you to write `g_autoptr(GPtrArray) arr = ...` to automatically unref arr when the scipe exits. One footgun that autocleanup has and C++ smart pointers don't is, that the cleanup function isn't called on reassignment, so reassigning on a autoptr causes the previous value to leak.
