Make ▷ (\triangleright) alias for |>

[AzamatB]

Would give the code with pipes a cleaner look:

[1:5;] |> x -> x.^2 |> sum |> inv

[1:5;] ▷ x -> x.^2 ▷ sum ▷ inv

More arguments in favor:

1. Does not hurt users, since if someone wants to use some "right-pointing triangle"-like symbol in the code he still has plenty of alternatives available:

   ▶, ▸, ▹, ►, ▻
◁, ◀, ◂, ◃, ◄, ◅

so won't need to resort to piracy

2. Many coding fonts with ligatures (notably FiraCode) already turn |> into ▷

▷ currently has multiply-like precedence, so that would need to change. Does anybody know if/why this would be multiply-like?

One usage of this type of symbol is for normal subgroup notation
