newTemporaryLocalVariable

back to summary

public TemporaryLocalVariable newTemporaryLocalVariable(int index)

Temporary local variables are immutable and always start from a low index value and increment up to a higher index value per scope. So we can share these and store the ones in a simple list. If hard pinning is ever an issue we can periodically evict the list and start over at the cost of more live objects but this list cache reduces a simple empty Rails app console from over 140K instances to about 1200 instances.
