Solved: How I Push and Pop vba system settings like Application.Calculation. Can it be improved?

For 25 years I have written hundreds of subroutines that did something like this.

Application.calculation = false
Call LongRunningSub
Application.calculation = true

That approach always reset the specific setting to its default value which is not what I really wanted.

Instead I wanted the following approach, but I never knew how to do it generically.
Push Application.calculation
Call LongRunningSub
Pop Application.calculation

Today, I finally figured out a fairly easy solution which I have shown in the attached .xlsm file. The above code becomes.
StackPush(aCalculation)
Call LongRunningSub
StackPop (aCalculation)

My Push routine is very simple (see the .xlsm file for the actual subroutines and more details).

Private stack As Object
Sub StackPush(ParamArray setting())
‘ see .xlsm for most current version of this routine
Dim item As Variant, curr As Variant
If stack Is Nothing Then Set stack = CreateObject("New:{4599202D-460F-3FB7-8A1C-C2CC6ED6C7C8}") ' CreateObject("System.Collections.Stack")
For Each item In setting
Select Case item
Case aEnableEvents: stack.Push Application.EnableEvents
Case aScreenUpdating: stack.Push aScreenUpdating
Case aDisplayAlerts: stack.Push aDisplayAlerts
Case aCalculation: stack.Push aCalculation
Case Else: MsgBox "110659 err"
End Select
Next
End Sub

So I am asking my fellow experts for advice and suggestions.

Have any of you ever seen a similar or better solution?
Do you think this idea is worthy of an experts-exhange article?
Do you think you would use this code yourself?
Currently, I support aEnableEvents, aScreenUpdating, aDisplayAlerts, aCalculation, and aCustom
what other settings should I support?
My .xlsm file currently supports pushing and popping of user defined variables. I wonder if that is a bad idea?
I currently have very little error checking. I feel that it is the developers job to make sure the Push and Pop calls match properly..
Any other improvements you can think of?
