Sometimes we would like to time the speed of some things for comparisons, but those things execute too fast to measure. So we arrange to put them inside loops, and then measure the loops. That is not very practical, because the loops in bash add too much overhead for the things we're trying to measure.
The usual way to deal with this is to measure the loop overhead and take it
into account. Adding a special variable is not the right way to go about
it.
If we're going to add yet another way to execute a command a specified
number of times (we're not), adding a repeat count here is not the right
way to do it, either.
