For general performance and also to get rid of the possibility of deadlock, we in some cases should utilize the difficult very low-stage “lock-cost-free” services
Flag goto. Greater even now flag all gotos that don't jump from a nested loop for the assertion quickly after a nest of loops.
The tips usually are not a random list of unrelated procedures where you can randomly decide on and choose using an expectation of accomplishment.
Yet another illustration, use a particular type together the lines of variant, instead of using the generic tuple.
