GetNewClosure和Start-Job(GetNewClosure and Start-Job)

 我无法理解GetNewClosure如何与Start-Job一起工作。 例如，我有以下代码 
 
function Test([string]$Name)
{
     $block = { Write-Host "Name = $Name" }.GetNewClosure()
     &$block
     Other $block
     OtherJob $block
}

function Other([scriptblock]$Block)
{
    Write-Host -NoNewline "In Other: "
    &$Block
}

function OtherJob([scriptblock]$Block)
{
    Write-Host -NoNewline "In OtherJob: "
    $j = Start-Job -ScriptBLock $Block
    Start-Sleep -s 1
    $j | Receive-Job
}
 
 在调用我得到的代码时 
 
PS C:\> Test "foo"
Name = foo
In Other: Name = foo
In OtherJob: Name = 
 
 请注意，在OtherJob中未捕获$ Name。 
 
 它可能与Start-Job启动一个新的PS实例有关，但是有没有解决方法（最好不包括使用-ArgumentList）？ 
 
 PS：版本表应该重要 
 
PS C:\> $PSVersionTable

I'm having trouble understanding how GetNewClosure works in conjunction with Start-Job. Case in point I have the following code
 
function Test([string]$Name)
{
     $block = { Write-Host "Name = $Name" }.GetNewClosure()
     &$block
     Other $block
     OtherJob $block
}

function Other([scriptblock]$Block)
{
    Write-Host -NoNewline "In Other: "
    &$Block
}

function OtherJob([scriptblock]$Block)
{
    Write-Host -NoNewline "In OtherJob: "
    $j = Start-Job -ScriptBLock $Block
    Start-Sleep -s 1
    $j | Receive-Job
}
 
When calling the code I get
 
PS C:\> Test "foo"
Name = foo
In Other: Name = foo
In OtherJob: Name = 
 
Notice that $Name is not captured in OtherJob. 
 
It is probably related to Start-Job starting a new PS instance, but is there any workaround for this (Preferably one that does not include using -ArgumentList)?
 
PS: The version table should it matter
