[tlaplus] Re: Understanding PlusCal 'either' translation to TLA

When you say "doesn't work" what is the behavior you're seeing?

I'm following Hillel Wayne's book car & traffic light example and found that doing

either

    do_something := TRUE

or

    skip;

end either;

In PlusCal gets translated to:

\/ /\ do_something' = TRUE

\/ /\ TRUE

    /\ UNCHANGED do_something

And replacing this with:

do_something' = TRUE \/ UNCHANGED do_something

Doesn't work.

Why aren't those equivalent?
