two related questions.

1. If I have an array with many size 1 dimensions why doesn’t `squeeze(arr)` find the one dimensions and remove them automatically?

2. And given it doesn’t what is the best way to make this behavior? I do `squeeze(arr, tuple(find(size(test) .== 1)...))` which makes me shudder.

I’m not sure why `squeeze` doesn’t have the option to remove all dimensions of length 1 automatically. I think we should define a `squeeze(A)` which removes all axes that have length one while keeping the currently definition of `squeeze(A, dim)` to drop specific ones.

I think the reasoning was that `squeeze(arr)` is type-unstable, so it’s best to avoid functions that have fundamentally poor performance.
