What would be the best way to add a loading bar (or just simple dots) to a map function

This is for maps that can take several minutes.

i.e.

```julia
function foo(x)
  sleep(x)
  x ^ 2
end

cur_range = 1:3

map(x -> foo(x), cur_range)

```

[GitHub - timholy/ProgressMeter.jl: Progress meter for long-running computations](https://github.com/timholy/ProgressMeter.jl) supports for-loops but not `map()`, but I bet it could be adapted for your use case.

You’re right.

There seems to be a pull request out for it already:

Also, you can already use a comprehension, so instead of `map(foo, cur_range)`, you can do `@showprogress [foo(x) for x in cur_range]`
