PowerShell: Is there an automatic variable for the last execution result?

I'm looking for a feature comparable to Python interactive shell's "_" variable. In PowerShell I want something like this:

> Get-Something # this returns an object and display it to the output.
# Now I want to assign that object to some variable
> $anObj = ???

No there is not automatic variable like that.

You have to do:

$output = Get-Something
$output
$anObj = $output

to get the behaviour
