Correct (as far as I am aware).

That's a qualified "yes".  You *CAN* use it, but with a caveat.  It is
against the C++ standard (ISO 14882) to use it, since identifiers that begin
with an underscore-followed-by-capital-letter are reserved.  (Also, any
identifier with the underscore-underscore sequence anywhere in the
identifier are reserved.)

That would be one reason to contemplate breaking the ISO 14882 rules.
