Problem Statement

Write a program which uses a timer (with the least granularity available on your system) to time how long a function takes to execute. Whenever possible, use methods which measure only the processing time used by the current process; instead of the difference in system time between start and finish, which could include time used by other processes on the computer. This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.

Let's start with the solution:

local(start = micros)
loop(100000) => {
	'nothing is outout because no autocollect'
}
'time for 100,000 loop repititions: '+(micros - #start)+' microseconds'
