Benchmark::progressbar is a combination of benchmark and term::progressbar that produces a simple progress bar illustrating execution of benchmark runs. as such, it is particularly useful for heavy benchmarking tests that take a long time to complete.

you can use it as a drop-in replacement for benchmark, but the only functions that would display a progress bar are: cmpthese, timethese and timeit.

this module is not compatible for use with benchmark in the same script. the author doesn't know of any case where this would make sense.
