Minor nit: 'register' is not a mandate, but an ignorable suggestion.
So a compiler either could or must ignore 'register' in able to make
'&x' possible.

Of course, the idea of ignorable keyword suggestion is itself somewhat
strange ;-)

I was certainly confused for awhile.  About the time I finally got it,
I switched to Python.  I *initally* understood *all* Python bindings
to be like C++ references (which in terms of the CPython
implementation is +- true), but the very uniformity made 'reference'
less confusing to me.

Interesting comments.  I'm glad you piped in.
