What is the idiomatic way to slice an array relative to both of its ends?

Question

Powershell\'s array notation has rather bizarre, albeit documented, behavior for slicing the end of arrays. This section from the official documentation sums up the bizarreness

Answer 1

I believe this is the right way to do it. all other methods require more code.

$a[1..($a.Count-1)]

Also, if array is converted to string it becomes easy to get data as below:

$a = 0,1,2,3
[string]::Concat($a).Substring(1)
