We are in the process of generalizing some code from scalar fields to vector spaces, and some algorithms that use * can be rewritten in terms of ⋅ (LinearAlgebra.dot). These algorithms support missing values in the scalar case because missing * missing is implemented in Base. Can we also have a dot(::Missing, ::Missing) = missing in the next release of the language?
