NAME Timer

Provides a simple timer function to measure runtime of a callable block. Returns the return value of the block and the time elapsed in seconds.


use Timer;

# Sum the reciprocals of 1 to 1000, 100 times and return
# the sum and the total execution time for the block.

say timer { my $i = sum((1..1000) »R 1) for ^100; $i }

# prints (7.485470860550344 1.5826559) (times will vary)


A simple timer, useful to evaluate run time of a callable block without needing to set up variables and calls to a time function.

Extremely simple and easy to implement, but I found myself writing it over and over when trying to refactor / optimize code, so I factored it out into a module.
