Great news! For others who can’t wait to try this out, you can run nix from the fork’s branch by:

nix run "git+https://github.com/rhendric/nix?ref=rhendric/pipe-operators" --  --extra-experimental-features pipe-operators repl

(this probably has no stability guarantees so YMMV)

I’ll definitely be switching from current stable to whatever release of Nix comes with this feature. Well, probably, once nixfmt also starts supporting this syntax.
