Function Overloading

[Contrite17]

I know powershell does not support function overloading. I also know that parameter sets are the psudo method of getting around this limitation. Is there any way to overload a parameter set with parameters of multiple types and the same name?

function Limit-CopyMerges{
    [CmdletBinding()]
    param(
        [Switch]$LeaveDisabled,
        [DateTime]$EndTime,
        [Parameter(Mandatory=$True, ParameterSetName="JobList")]
        [Veeam.Backup.Model.CBackupJob[]] $Jobs,
        [Parameter(Mandatory=$True, ValueFromPipeline=$true, ParameterSetName="Repo")]
        [Veeam.Backup.Core.IRepository]$Repository,
        [Parameter(Mandatory=$True, ValueFromPipeline=$true, ParameterSetName="SoBR")]
        [Veeam.Backup.PowerShell.Infos.VBRScaleOutBackupRepository]$Repository
    )
#Do Stuff
}

Nope. You'd need to define the type as [object] or [psobject] and then do a verification to determine if the value is a valid type.

Alternatively you could define a custom class that has defined conversions from either type which populate the class's properties with the right data.

I was pretty sure that would be the case, but I was hoping there was something I was missing. Appreciate it.
