- On redeferral, remove FunctionBody's from the dictionary on the source info. That dictionary is non-leaf and pins the contents; changing it to leaf seems feasible and is recommended by a comment, but it seems best to do it outside this change. 2. Handle re-use of FunctionBody for which we've already allocated literal regexes. 3. Add some rudimentary redeferral tracing, to which I'll add this week.
eligible for deferred parsing (e.g., not arrow functions, not functions-in-block). This is experimental behavior, off by default. Define an 'on' mode in which all eligible functions are redeferred on GC, as well as a 'stress' mode in which all candidates are redeferred on each stack probe. This change is built on a previous PR that refactors the FunctionBody hierarchy to make it easier to toggle between deferred and fully-compiled states. 1.
