concept/requires keywords are not highlighted

I have 1.45.1 VSC and 0.28.1 C++ extension and concept/requires keywords are not highlighted even though VSC clearly knows(they're suggested) that they're C++ keywords.

@Colengc does the extension support _concepts and requires_ keywords for enhanced colorization? Or is this a feature request?

'concept' and 'requires' are syntactic tokens. Semantic parsing is not required to identify them. Syntactic colorization comes from VS Code and TextMate grammer. So, I believe this would be a VS Code issue.

The issue may be tracked by:

jeff-hykin/better-cpp-syntax#396

The TextMate grammer from that repo is contributed to VS Code. Often changes are available in the "Better C++ Syntax" extension before they are available in VS Code. Using the latest version of that extension, concept and requires are colorized.

Closing this, as we don't generally keep tracking issues open in this repo for issues with VS Code's TextMate grammar. Since this has been addressed in the Better Syntax extension, it should just seem to be a matter of time until VS Code gets an updated grammar.(?)
