UndefRefError from doc

[adkabo]

The stacktrace doesn't mention StaticArrays so I'm guessing it's a stdlib issue.

julia> using StaticArrays

julia> SizedVector
SizedVector{S, T} where {S, T} (alias for SizedArray{Tuple{S}, T, 1, 1, TData} where {S, T, TData<:AbstractArray{T, 1}})

this fixes it:

I could not make a simple MWE though

Another example, possibly the same issue.
