Broadcasted piping .|>

Seems like this ought to work:

julia> @_ 1:4 .|> float |> filter(iseven(Int(_)), __) .|> sqrt              
#27 (generic function with 1 method)

julia> 1:4 .|> float |> xs -> filter(x -> iseven(Int(x)), xs) .|> sqrt 
2-element Array{Float64,1}:
 1.4142135623730951
 2.0

Fix also allows this, in which __ now sometimes means an element, I think that's OK:

julia> @_ 2 |>  __ .+ (1:3)  .|>  __^2 |> filter(isodd(_), __)
2-element Array{Int64,1}:
  9
 25

__ now sometimes means an element

I guess this should work, odd as it is!
