Description
Some ideas;
- Shapes, like multiple constructors with records in a single unboxed variant, where we can figure out which record is which at runtime (by checking distinct props, etc)
- Tuples
Especially the first one pops up here and there when interoping with JS, and would be a fairly large capability improvement to have.

Research direction
The issue names no files, tests, or entry points. Begin by locating the compiler implementation of unboxed variants, then determine how record-shape discrimination and tuple support should work; done would require an agreed design and coverage for the proposed advanced cases.
