Interesting.
I’m sometimes clearing and reusing tables to avoid dynamic memory allocations in realtime systems (games). Does this mean that there’s some catastrophic slowdown in some rare case? If so, I’d definitely need to revise my coding practices.
Does the issue only occur with arrays? Are pure dictionaries also affected?
