Just curious, was this causing real issues? Unary minus on unsigned values should not really be an issue afaik, although I agree that being explicit is probably a good idea?

No functional issue, I was just seeing a warning in VC++ and looking at the code it's not clear what the behavior is when values are unsigned. Looking around it appears to be speced behavior, but still didn't feel intuitive.

I removed the template parameters from the operator overloads to push the burden of casting out of aliased buffer. It now expects the correct type to be passed to it and will generate warnings at the site rather than in the
AliasedBuffercode.EDIT: These warnings were generated by the VC++ compiler.
