Why do most (at least JS) parsers restrict syntax errors to a single position? eg. only a single column/line, rather than having a range of start/end? The errors would be a lot richer.

Don't they? TypeScript has it, though it only presents line/col on the command line. You can see that it's a full range if you use --pretty though.
