Add Object to container in Powershell

I am trying to add objects to a container in Powershell:

function Person {
  param ($FirstName, $LastName)
  $object = [PSCustomObject]@{
    a=$FirstName;
    b=$LastName
  }
  return $object
}

$container = New-Object -TypeName System.Collections.ArrayList

$result = Person "Billy" "Kid"
[void]$container.Add($result)

[void]$container.Add(Person "Bob" "Hope")
[void]$container.Add({Person "Mad" "Max"})

 foreach ($ob in $container) {
   Write-Output $ob."a"
 }

$container

This line:

[void]$container.Add($result)

works, meaning that the correct value gets printed in the foreach loop. But the lines:

[void]$container.Add(Person "Bob" "Hope")
[void]$container.Add({Person "Mad" "Max"})

does not. Is it not possible to add an element to the container using a function call?

You need to evaluate the expression Person "Bob" "Hope" before you can add it.

You can do this easily like this:

$container.Add($(Person "Bob" "Hope"))

(Note the added $()).
