Disable positioning parameter binding in Powershell

Question

I want only parameters via an alias:

script.ps1 -d site1 -c eac34b2d

This should not be allowed:

script.ps1 site1 eac34b2d

Param( [parameter(Mandatory=$true)] [alias("d")] $DocRoot, [alias("c")] $Commit ) 

Answer 1

Basically, you want to disable position snapping. I wrote about the built-in Powershell 3.0

A workaround for v2 is available here:
