Drop everything known about mutable record fields.
Drop everything known about mutable record fields.
A simple escape analysis would help here. Some of the records we track never leak to other methods, therefore they can not be changed. We should not drop their bindings in this case. A closure object would be such an example. Some complications:
- outer pointers. An closure escapes as an outer pointer to another nested closure.
