Significant Indentation: Mixing Tabs and Spaces

[morgen-peschke]

While tooling is a concern, I’m a bit more worried that the feature freeze thread seems to indicate this will become part of Scala 3 without going through the SIP process, despite its controversial nature.

@odersky

All new features are already implemented and documented in the Dotty codebase. What we plan to do is that instead of force-fitting them into the standard SIP framework we will add status information to the Dotty reference pages
