I'd like to see languages like that, but it's a massive lift. Our systems of source control and CI/CD are built around the assumption that languages are text files that are somewhat line oriented. It's valuable for people to be able to use different editors and tools, and text files are the integration point that makes this work.

Fallible parsers are a bit of a hack but they're a hack that works and is widely deployed already, and I'm not convinced the value of moving to a symbolic/binary representation creates enough value to justify the risk involved in the migration. That being said I'd love to see it happen. We'd end the tabs and spaces debate once and for all!
