how to print progress of a long running parallel() loop?

[mw]

https://dlang.org/phobos/std_parallelism.html#.parallel

auto logs = new double[1_000_000];

foreach (i, ref elem; parallel(logs))
{
     elem = log(i + 1.0);
}


In Python, using joblib, I can use `verbose` level like this:

r = Parallel(n_jobs=2, verbose=10)(delayed(sleep)(.2) for _ in 
range(10))

to print out the progress.

How to do this in D's parallel loop?

thanks.
