alice-teacher For-loop complicated version doesn't show index change when watching the variable

[Donald Slater]

Again, Thank you very much for this bug catch. I have forwarded the sto the dev team, with a project that demonstrates the issue.

I am not sure of the underlying implementation of the loop and the complicated representation of it. It may very well be that the Watch this Variable  window / system is created and displayed before index comes into scope. In that case. “Watch this variable” should not be an option for this variable.

Thank you,
Don Slater

To our surprise, it said "None" the entire time. So we created a myIndex number variable, set its value to equal index somewhere inside the loop and watched that variable change to see for ourselves that index is indeed keeping track of the iterations.
