There is the concept of PSObject and Add-Member that you could use.

$contact = New-Object PSObject

$contact | Add-Member -memberType NoteProperty -name "First" -value "John"
$contact | Add-Member -memberType NoteProperty -name "Last" -value "Doe"
$contact | Add-Member -memberType NoteProperty -name "Phone" -value "123-4567"

This outputs like:

[8] » $contact

First                                       Last                                       Phone
-----                                       ----                                       -----
John                                        Doe                                        123-4567

The other alternative (that I'm aware of) is to define a type in C#/VB.NET and load that assembly into PowerShell for use directly.

This behavior is definitely encouraged because it allows other scripts or sections of your script work with an actual object.
