Research direction

No source file or test is named in the report. Begin by reproducing the C++26 pack-indexing example in IntelliSense, then trace the syntax handling and colorization paths; done means no error squiggles and correct coloring after pack indexing.

Written by the indexing model from the issue text.

Description

bug Language Service parser
Feature Request
Image

IntelliSense does not recognize pack indexing syntax and because of that it shows error squiggles and also colorization of some statements is wrong after a pack indexing usage (in the example test_concept is colored incorrectly).

Please add support for pack indexing.
