The last two are of my recent doing. I have been trying to clean up the
functionality of special matrix types in Base.LinAlg; however, the current
state of affairs is that any new methods I try to implement on the basic
matrix types keep leading to method ambiguity warnings downstream, and a
meaningful resolution of them probably won't be possible until
#987<https://github.com/JuliaLang/julia/issues/987>is resolved.
