The problem with code that has pre- and post-addition setup is that now you
have two objects in the stack, which complicates your stack frame. The
compilers aren't currently smart enough to deduce std::unique_ptr whose
payload is completely null and can be early-destroyed.
I'm wary of making user code less readable, but it's something we should do if
it's for a good reason.
