What is the future of `sin(::Vector)` when there is `sin.(::Vector)`?

I think the behaviour that sin.(x::Number) == sin(x) should not be seen as the result of numbers acting like vectors, but rather that broadcast(f,x::Number) should return a Number.

Another reason for this is that, in 0.6, operators like .+ are planned to be broadcast calls. By longstanding convention, such “dot operators” behave like the ordinary scalar operators when acting on scalars.
