The @ character is not part of the basic character set for C or C++, and
is not in use in the standard language.  The only use I have seen for it
is in extensions in compilers for embedded systems as a way of giving
fixed known addresses to variables (typically memory-mapped
peripherals).  I haven't noticed it in any current language proposals
either.

The most common suggestions I have seen for rotation operators are <<<
and >>>, which have the advantage of not needing new characters or
interacting badly with existing usage.  (I still don't think such
operators make sense - but these are perhaps the least bad choices.)
