|
Refactoring of string internals. Existing tests pass.
Adding tracking for multiple string heaps, or "scratchpads."
Cases of allocating across different pad contexts aren't implemented yet.
Adding basic controls to manage these contexts, which lead to expected assertion failures
at unimplemented cases.
