This is perhaps out of scope for this group, but I’ve actually long wanted languages to move in a direction where indentation is not present at all in the source file—your git repo might never have an instance of /\n[ \t]/ in it. Instead, it’s automatically added by the IDE while displaying the code, based on the block beginnings and endings present in the actual source. This would make incorrectly indented code a thing of the past; it would also be obvious when you’re missing a curly bracket, because your code would be indented all wrong. And it would end the destructive whitespace wars, because everyone could just set their IDE to do whatever they liked best.
