Hello all, I've been cleaning up the JavaScript grammar and as I get started on this next round of cleanups, I've run into some inconsistencies in the grammar that have led to the following questions:
* When adding a language specific implementation of a grammar group, like comment.block for JavaScript, should the name of the group be comment.block (expected) or comment.block.js (What's there now)? (I can't tell if I use the name that corresponds with the root group, comment.block, or if I add the language name to the end like comment.block.js.)
* Is there a way to have certain grammar features enabled based on the existence, or lack of, a certain "enabler" in the file? (For example, JavaScript has a strict mode to mark extra words as keywords due to potential plans for supporting them as keywords in the future. That being said, if you have "use strict;" in your file, certain keywords should be scoped that wouldn't be otherwise *and* variable names with those keywords should be marked as invalid.)
* Why isn't 'null' treated as a constant like undefined/Infinity/NaN? Right now it's constant.language.null.js but I'd expect it to be constant.language.js.
These questions, while specifically about JavaScript's implementation, are really general questions about naming, feature enablement and what defines when you break away from root groups and define your own groups. Any help would be appreciated.
