Refcounting in single threaded CPython works ok.  It has caused a lot of
pain with multi-threading because have to put locks around the refcounts
(killing performance in the single threaded case), or lock the whole
interpreter (the infamous Global Interpreter Lock or GIL) when executing
bytecodes.  One "advantage" of refcounts was that objects are freed as
soon as the last reference disappeared, so people relied on that for
timely release of stuff like file descriptors, a lame style imho.  Later
the "with" statement was added to Python which explicitly releases stuff
at the end of its scope, which is preferable.  

Micropython uses pure gc instead of refcounts, if that matters.

That article is pretty unpersuasive.  C++ smart pointers work pretty
well if you remember that C++ is a totally different language than C and
don't use legacy C stuff in your program.  The refcounted pointers are
useful when they are needed, but unique_ptr is good enough most of the
time, and has almost no overhead.  unique_ptr means the pointer has a
single owner, so the object is freed when the owner goes out of scope,
unless you transfer the ownership to another unique_ptr first.

C++ std::shared_ptr (the ref counted ones) do have locks around the
refcounts, which must be expensive.  I believe Seastar has its own
version of shared_ptr that can't be shared across threads, so that would
get rid of the need for locks.

There's some hooks in C++ for a real GC but I don't know of any
implementations or what the obstacles to them are.  But, part of the
idea of C++ is to control your program's memory resources.  If you want
a GC'd language you might as well use one designed for GC from the start.

Yes, that's way cool.

I think it's worth supporting the return and locals stack in specific
implementations using carnal knowledge of those implementations.
