You can define the operator `..` do broadcast `getindex` and `getfield`, see

> I often find myself wanting to broadcast getindex and getfield, which is perfectly doable, but could enjoy a nicer syntax. I figured out if I define the operator .. in the right way, I get a kind-of nice syntax for doing this without macros: a = [randn(3) for \_ in 1:4]; b = [complex(i,i+1) for i in 1:4]; (..)(x::AbstractArray,i...) = getindex.(x,i...) (..)(x::AbstractArray,i::Symbol) = getfield.(x,i) julia\> a..2 == getindex.(a, 2) true julia\> b..:re == getfield.(b, :re) true Edit: To broadca…
