@pinpox @nixos @tcl @clacke I (@alecui) haven't seen any examples, mostly because from what I have experimented with the integration I haven't found anything that integrates nicely with NixOS (perhaps because it's not quite a popular OS around these parts). From my memory though Nix has official Perl bindings so you could interop through one of the available CPAN modules. You can contribute to the Tcl community in that regard, we encourage your efforts :)
