I hope this is the correct place to report this.. but I have what I think is a bug with the highlighter when it sees things like this:

            in entry == "regular" && builtins.match ".*default\\.nix$" name != null)

I get this error:

Current master is substantially different from what was shipping when this was filed (ABI 15, updated builtins, refactored injections/highlights). If 'Highlight Error' still reproduces, please paste the exact .nix snippet and describe what's wrong — one concrete example is enough to trace it. Keeping open for now.
