01-button.elm has syntax errors about elm-architecture-tutorial HOT 5 CLOSED

I am assuming you are doing the exercise in the Elm Guide to implement "Reset". You are attempting to redefine the value of model.

Try this instead:

...
    Reset ->
      model - model

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

@zky829 Could you post or point to the code (the copied one on your machine)? It'd be clear if we see the copied code. The error message is obvious though.

Also works:

...
    Reset ->
      0

It looks like @sr-ix has a good theory of the root cause here. The example works for me, so I am not able to reproduce with the information here.
