ERROR: MethodError: no method matching NamedDimsArray{(:_,),T,N,A} where A<:AbstractArray{T,N} where N where T(::Int64)

Correct answer is:
14
Not a Array at all, just a scalar.

I presume we want to require names match? so (once fixed) this should error?

a = NamedDimsArray{(:a,)}([1,2,3])
b = NamedDimsArray{(:b,)}([1,2,3])
a' * b

What about for dot? Would we want dot(a, b) to error?

Note that dot ignores dimensionality (and check only length), so dot(a, a) == dot(a', a) == dot(a, a') == dot(a', a') (which is probably the correct behaviour, but may not be JuliaLang/LinearAlgebra.jl#641 ...and is anyway maybe surprising at first)
