When template aliases become available, to use them you'll need to replace 'rebind_alloc' which will break any code which uses the 'other' member. If you used a different name then you could leave that in alongside the template alias so that existing code would continue to work.
True - although I prefer to have a clean break for conformance. (We've got a bit of "retained" code for back-compat that I'd like to nuke someday; the exception being tr1 using-declarations since those are not really doing any harm and their usage was very widespread.)
It'd also have been a more useful error message, if it just said that 'rebind_alloc' isn't available, I'd have instantly known what the issue was, instead there was an odd error about 'value_type'.
That's a good point. I'm sorry I didn't think of it earlier. (Unfortunately it is far too late for me to change anything for VC11 RTM that doesn't involve fixing a kitten-liquefying bug.) STL
