Powershell function creation with Set-Item and GetNewClosure

Vote count:

I am attempting to build a function that can itself create functions through the Set-Item command where I pass a scriptblock for the new function to the -Value parameter of Set-Item. I'm running into an issue where using GetNewClosure on the scriptblock doesn't seem to be working and I just don't know what I'm doing wrong.

In the code below, first I'm creating a function manually (testFunc) which works as intended, in that setting $x to 2 after the function creation will not cause the function to return 2; instead it returns 1 because that was the value of $x at the time the function was created. But when I try to do the same through the make-function function, the behavior changes.

I'm sure I'm overlooking something small.

> $x = 1
> $block = {$x}.GetNewClosure()
> Set-Item function:global:testFunc -Value $block
> testFunc
1 

> $x = 2
> testFunc
1 # still 1 because of GetNewClosure - this is expected behavior

> $x = 1
> function make-function { $block2 = {$x}.GetNewClosure()
       Set-Item function:global:testFunc2 -Value $block2
  }
> make-function
> testFunc2
1 

> $x = 2
> testFunc2
2 # Why is it not returning 1 in this case?
