Improve efficiency for context snapshots #39

Open albertZhangTJ opened 1 month ago

albertZhangTJ commented 1 month ago

Currently, before generating each component of a production rule, a snapshot of the context is taken. This is a rather expensive action yet the snapshot is rarely used.

We can improve the performance here through having the tester specify the parts where back-patching is possible and only take snapshots for those components.
