I would love to see a₁ automatically call getindex(a, 1). It would make
math easier.
I'd love to be able to write:
b = μ₂ + Σ₁₂*(a₁ - μ₁)/Σ₁₁
Λ = Σ₂₂ - Σ₁₂*Σ₁₂/Σ₁₁
for μ::Vector{F<:Real}
and Σ::Matrix{F<:Real}
Σ could be accessed via Σ₁₁ to get Σ[1,1]. Of course this breaks down with
digits larger than 9, but you probably don't want to be using this feature
for such large values.
