Steven - are you OK with the changes I've committed to the sandbox? I'm still not 100% happy with the angle syntax, but it isn't obvious to me how to improve it...
You're misusing dimensionless_quantity.... Did you run the tests and examples?
I'm also a little concerned about the runtime optimization issues raised - I'll take a look at the assembly generated by gcc. I was particularly surprised by the Intel compiler performance. I believe Intel bought the KAI C++ compiler that was well known to be extremely good at optimization in the presence of template code (in particular expression templates)...
We could try comparing it to a simple wrapper. If that is slower than double than there is nothing we can do to improve perfomance. In Christ, Steven Watanabe
