Description
Description of the problem or steps to reproduce
It isn't possible to color different groups differently in syntax files. For example, I'd like to color proc calls:
- identifier.class: "\\w+(?=\\()"
because re2 doesn't support lookahead, it's not possible using this way. However, it could be possible to do the following:
- pattern: "(\\w+)(\\()"
groups: [ "identifier.class", "default" ] # color group 1 as identifier.class, and group 2 as default
which would eliminate the issue.

Research direction
Start with the syntax-file format and the pattern/groups configuration shown in the issue, then trace how regex matches are assigned colors. Check the requested behavior against the stated RE2 limitation. Done means separate capture groups can receive the listed colors when a syntax file uses the proposed configuration.
