In general I think we could do with a bit more documentation in that area, yes. For example, it's fairly obvious that HLSL_OP3_LERP takes 3 arguments, and it seems safe enough to assume it does a linear interpolation between two of them, but I don't think it's necessarily immediately obvious which argument is the start, end, or interpolation factor.
