That is slightly weird 🤔 ... Why not $(which hydra-node) too for consistency? I mean, this boils down to the same thing given how it is invoked but, I don't know, the example feels off to me 😅

[ch1bo]

It is kind of highlighting both ways. The hydra-node executable would only be in scope if one would be using the nix-shell -A demo environment and below we also use cabal exec invocations. Not sure which way is more clear 🤷
