Recognize begin and end as keywords when used in array indices

[steffenhaug]

A lot of text editors recognize begin and end in array indices as keywords.
Granted, they probably do this because they are stupid and just highlight based on regex, but given that begin and end are special when used as array indices I think it makes sense to highlight them.

It might be sensible to highlight them as something else though, to distinguish them from their counterparts when used outside array indices. I'm open to suggestions.

It's already in place, see lines 317:323. The trouble is the capture @variable.builtin which is not defined in Zed's default color themes. It falls back to @variable and that's probably just your default foreground color. You can experiment in your ~/.config/zed/settings.json:

{
  "experimental.theme_overrides": {
    "syntax": {
      "variable.special": { "color": "#ff0000" }
    }
  }
}

We're discussing how to make these customizations better visible (#13). A better default could help too 😆.

You may also be interested in this draft. Having a reference file for different editors would make the maintenance easier.

Oh, that was silly of me 🤦 Thanks for clarifying! It was indeed an issue with the theme.
