Daily Godot Tip #39: You can create code regions between #region and #endregion that allow you to collapse that entire section into 1 line
Useful for things you don't edit but still would need to scroll past
This makes more sense, to me, to be stored in some IDE project config file than be present in and cluttering up the actual source code. This should be an IDE feature instead of a language feature IMO
I think having region boundaries part of the code makes sense. Is the alternative having file and line number references somewhere else? They could fall out of sync all too easily.
But the open/collapsed state of the regions? That should be per-user IDE state, the last thing we want us that becoming diff noise in the repo.
I just disagree, but that's okay. This is about presentation of code to the viewer which makes it a responsibility of the IDE and not a responsibility of the language. You're right that the line references would need to be kept in sync, but I think that would be trivial.
