Or maybe I still don't understand. Are these forward declaration partial specializations strictly necessary? Yes. It's a means to prevent unwanted ODR violation. Fusion is modular. The support for boost::array comes when you include a

Agreed. But we certainly need workarounds for compilers that can't handle an incomplete partial specialization. On head, xpressive doesn't compile on cw-9.4 because of this problem, and that's a regression from 1.34.
Agreed. I intend to go back to the Mac anyway, after a long trek into Wintel. Sorry if this may be OT but is virtualization really working well for developers? I'd love to get, say, VisualC++ along side CW. Also, is CW not a dead-end? It's a pity that they no longer have the Windows version.
Nokia is using a CW9.4 Windows x86 compiler to build emulator applications for their Series 60 devices. Not sure if it can be used to build standalone x86 applications though. - Michael Marcin
