`(benchmark-run [iterations] ?code)`syntaxRuns the

**?code****iterations**times and returns an alist with the following keys:- min - the minimum runtime of all iterations in microseconds
- max - the maximum runtime of all iterations in microseconds
- mean - the average runtime of all iterations in microseconds
- standard-deviation - the sample standard deviation for the given runtimes

If

**iterations**is not given then**curren-benchmark-iterations**is used.
