No it didn't, that post created a new class called "FixNum"

And again, that's beside the point, which is to allow the expected "++"
semantics for immutable Numerics while also allowing in-place incrementation
for other classes which may store a mutable value, such as counters (whose
backing store may be a database, memcache, etc)

That would provide a truly Ruby-like ++ experience, aside from the fact you
can't redefine #++ for a Numeric, which probably isn't a good idea anyway.
