Can you mimic PowerShell v3 once you have installed v4?

I want to emulate PowerShell 3.0

From PowerShell v3 or v4 you can emulate v2 with this command:

%windir%\system32\WindowsPowerShell\v1.0\PowerShell.exe -version 2

$Host reveals: Version: 2.0

However, in PowerShell 4

%windir%\system32\WindowsPowerShell\v1.0\PowerShell.exe -version 3

$Host now reports: Version: 4.0 (I was hoping for 3:0)

Question: Is there any way of emulating PowerShell 3.0 from 4.0?

No, it's not possible. V4 is backwards compatible with V3, so any script written targeting V3 will work fine with V4.

If you want to write scripts that support both V3 and V4, it's best to use a machine/VM with V3 installed to make sure you don't rely on V4 features.
