- mpweiher 2y ago> objc_msgSend [...] does require malloc, Are you sure about that? ]pwd objc4/runtime/Messengers.subproj ]rg malloc ] The two variants I implemented way back when also did not require malloc. And of course NeXT used objc_msgSend() in the kernel, to good effect, so that's pretty low-level.
