I start having a bit of experience with decltype and VC compilers (sigh) through my eUML front-end for MSM and I can give you one reason: because it's probably not just VC10. I have here and there this problem (and others) with VC9 too. It might just happen in different conditions.
This is NOT the same issue. VC9 does not have the decltype keyword. We're not talking about typeof emulation. Please don't take us off-topic.
The issue is whether the decltype keyword is too broken on VC10 to define BOOST_NO_DECLTYPE. I think it /may/ be, so we should define it just to be safe, at least for 1.43.
I agree. There's more than one bug in VC10's implementation of decltype. The following directly impacts result_of: https://connect.microsoft.com/VisualStudio/feedback/details/541365/decltype-... Note the comment by Jon Caves that this won't be fixed in the VC10 release.
