Vista - Issue: getting/setting variable content using Get/Set-Content

I was playing with getting/setting variable content using Get/Set-Content and
variable provider and found this:

$x = 'Hi'
gc variable:\x
Hi

sc variable:\x -Value 'Hello'
gc variable:\x
Hello

sc variable:\x -Value (gc variable:\x)
gc variable:\x
Get-Content : The member "PSPath" is already present.
At line:1 char:3
+ gc <<<< variable:\x

What happens?

This is a bug. Here's what's happening. When an object is returned from
get-content, we attach a note property called PSPath that records where the
object came from. This allows you to see where you got the object from:

PS (1) > get-date > foo.txt
PS (2) > (get-content foo.txt)[0].PsPath
C:\Temp\foo.txt
PS (3) > (get-content foo.txt)[1]

However - if the object already has such a property, then an error occurs
since, by default, we don't overwrite existing properties:

PS (25) > $a = 1 | add-member -mem noteproperty PSPath foo -pass
PS (26) > $a
1
PS (27) > get-content variable:\a
Get-Content : The member "PSPath" is already present.
At line:1 char:12
+ get-content <<<< variable:\a

We need to modify get-content to force an overwrite of the PSPath property
if it already exists...
