- const structures can inherit from another, and update select fields.
- 'use' labels *must* appear in case statements.
- 'then' can extend a case section into some other.

## Needs Design
+- const arrays that are initialized incrementally throughout the code,
+ and post-processed at compile-time, e.g. to sort or derive LR tables.
+ Maybe even across modules.
+ Need a syntax
- union types - how do I want to support these? inheritance with variance?
- lambda
- 'error' value for various types. NIL for pointer NaN for float, extra flag bit
