How to use Benchmark class

[mahmoudajawad]

I'm unable to figure out how to use Benchmark class.
What I'm trying is:

from Benchmark import Benchmark

fn _iter():
    for i in range(10000):
        pass

Benchmark().run[_iter]()

[czheo]

from Benchmark import Benchmark

fn bench() -> Int:
    fn _iter():
        for i in range(10000):
            pass

    return Benchmark().run[_iter]()

print(bench())

This compiles but always return 0 in the playground.
