Implement ForEach Iterator in Powershell

I have created a custom class in PowerShell which I would like to be able to access via the foreach command.

In PHP, I can do this by using implements iterator in my class declaration and implementing some variables and functions. Is there something similar in PowerShell? How do I let my PowerShell class be accessed by foreach?

Note: I'm using PowerShell Core

You can extend some IEnumerable implementation like this:

class Test : System.Collections.Generic.List[PSObject]
{
    Test($items)
    {
        $items -split ';' |% { $this.Add($_) }
    }
}

$test = New-Object Test('a;1;x;y;z;2;3;4')

foreach ($item in $test)
{
    Write-Host $item
}

The result:

a
1
x
y
z
2
3
4
