具有功能和开关的PowerShell Native Cmdlet Set-Alias

Question

Question: Is it possible to set an alias that calls both a function and a switch?

Here is an example I am working with.

Set-Alias -Name myidea -Value 'Test-FunctionIdea -SwitchIdea' 
function Test-FunctionIdea {
  param(
    [switch]$SwitchIdea
  )
  if($SwitchIdea)
  {
    Write-Host 'Good Idea'
  }
}

Here is the error I am having:

myidea : The term 'Test-FunctionIdea -SwitchIdea' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if 
a path was included, verify that the path is correct and try again.
At line:1 char:1
+ myidea
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (Test-FunctionIdea -SwitchIdea:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

If it is possible please let me know how it's done. I've searched the internet for this and came up with no results.

You can check $MyInvocation.InvocationName and adjust the parameters inside the function:

function Some-Function([switch] $foo) {
     if ($MyInvocation.InvocationName -eq 'foo') { $foo = $true }
}

Set-Alias foo Some-Function

The [usually negligible] advantage is that it doesn't create an additional execution context for the new function scope.
