Playing with Measurements(1) recently, I was confronted with the fact that it does not initialize a base unit for either 2D or 3D angular measure. In SI units, these are measured in radians and steradians, respectively. The interesting part is that they're not base units in the SI table either. Technically speaking, an angular radian measure equates to a length/length. So I could define them as a unit derived from the Unitless unit. However, I'm not sure what use that association would be to users of Measurements. So, I'm tempted to make them "base" units, and just let them be measures in their own right.
I'm curious, what would you do? If you were architecting such a system, or use the current Measurements package, what would you do with angles?
(1) Measurements is a package found in the Open Repository. It allows for unit'd numbers to be created, done math with, converted, etc. It does automatic reduction. It's really kinda slick if you do anything that has to deal with mixed units of measure.
