I should clarify that "C++0xA" is a cheeky informal name for the next ISO Standard C++ language, due out soon. It had been labeled "C++0x" on the expectation that that would become "C++09" after release this year. "0xA" is the C++ (and C) hexadecimal notation for the decimal value 10. The name "C++0xA", then, implies the pessimistic expectation that it is delayed to 2010. To me the opportunity to call it C++0xA is reason enough to delay its release.

In which case it would be C++0A, not C++0xA.

It'll probably be C++1x (e.g. C++10, C++11, whatever). There has been no formal decision to go with hexadecimal numbering that I'm aware of. Informal discussions between committee members have been pretty mixed between continuing with a C++0x moniker or using C++1x.

"C++98" was never a formal name. The formal name is "ISO 14882:1998". Whether "C++10" or "C++0xA" wins out (or, indeed, C++0xB) is purely a matter of popular usage. You (and you, and you!) can help swing it the way you want.

\begin{pedantic}
NOT "C++0xA". The "x" is a wild card which under normal expectations would be replaced with an element of [0-9]. The joke is that since "C++0x" is taking so long. We (they) will keep the implied promise of a first decade delivery by extending the membership of the wildcard to [0-F] (hex).

That means that if you replace the "x" with an "A", you write it as "C++0A" not as "C++0xA"!.

In any case (as pointed out elsewhere), the name is not the real name for the language. It is a joke. The "official" non-real name will surely be of the form "C++1x".

I think that the joke is funnier if you interpret the "0x" as the hexadecimal prefix in C and, well, C++; so "0xA" is "10" in legal C. Therefore decimal "C++09" is followed by hexadecimal "C++0xA".

But 0 as a prefix means octal, so 09 is actually an illegal constant. :-(

Well then, fools were we to expect that an illegal C++09 would ever be released!
