Okay, weird title, again, I know. In the past few weeks I have really seen a lot of scripts that go far past the prepackaged notion of a PowerShell instance into the mechanics of the [PowerShell] object. Im just using the type accelerator here, but, underneath, the full type is System.Management.Automation.PowerShell. As shown below, the [PowerShell] type accelator is the same thing as the full name.
PS>[PowerShell]
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True False PowerShell System.Object
PS>[System.Management.Automation.PowerShell]
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True False PowerShell System.Object
So, when we work with the [PowerShell] type accelerator, we know what we are hitting against. To get more of an idea of what lives in this namespace:
PS>[powershell].GetMembers() | ft name, membertype-AutoSize
Name MemberType
---- ----------
get_Commands Method
set_Commands Method
get_Streams Method
get_InstanceId Method
get_InvocationStateInfo Method
get_IsNested Method
get_HadErrors Method
get_Runspace Method
set_Runspace Method
set_RunspacePool Method
get_RunspacePool Method
get_HistoryString Method

Quite a few things live in here. Eliminating duplicates shows this narrowed down list:
[powershell].GetMembers() | select name, membertype -Unique | ft -AutoSize
