Terminating a script in PowerShell

I coincidentally found out that <code>Break <i><UnknownLabel></i></code> (e.g. simply <code>Break <b>Script</b></code>, *where the label `Script` doesn't exists*) appears to break out of the entire script (even from within a function) and keeps the host alive.
This way you could create a function that breaks the script from anywhere (e.g. a recursive loop) without knowing the current scope (and creating labels):

Function Quit($Text) {
Write-Host "Quiting because: " $Text
Break Script
}

I thought up a neat little trick to do just that, when I wanted a function to exit a script without throwing an error, but not exit the console if the function was used from there. It involves the `$MyInvocation` automatic variable's `CommandOrigin` property.

```powershell
if ( $MyInvocation.CommandOrigin -eq 'Internal' ) { exit }
```

If the function is ran from the console, the CommandOrigin will be Runspace.
