This thread is from 4.5 years ago, the landscape was quite different back then 🙂  
With [DataPipes.jl](https://discourse.julialang.org/t/ann-datapipes-jl-0-3-0/60734), one can write the original example from the first post basically without any changes, and continue using `.|>`:

```julia
julia> @p 2 |> __.+ (1:3) .|>__^2
3-element Vector{Int64}:
  9
 16
 25

```

> **or use \`map\` as you suggest**
>
> ```julia
> julia> @p 2 |> __.+ (1:3) |> map(_^2)
> 3-element Vector{Int64}:
> 9
> 16
> 25
> 
> ```
