Broadcasting for nested structs

[XLin0mu]

When I'm dealing with a nested structure, I have to use many circle structure if I wanna traverse more than a layer in a nested structure.
I mean, do we need a new operater like "dot dot" which's similar to the dot operater, to implement multi-layer
nested structure traversing?
For example:

a = b = c = h = rand(10, 1)
d = e = f = [a, b, c]
g = [d, e, f]
ar = Array{Any, 1}(undef, 3)

Usually I do this:

for i in 1 : length(g)
    ar[i] = g[i] .* h
end

Could we make a "dot dot" operater working like this:

ar = g ..* h

or some forms look more scientific.
Actually I don't have a nice idea on forming this operater, if you think it's a good idea as well, I believe you can struct a great operater for us.
Sorry for bothering.
