Re: [tlaplus] tlapm Error

It looks like one of those cases where the PM parser does not agree with SANY. The most likely culprit is a construct involving tuple binding, but there are a few other cases. These problems are expected to disappear with the next major release of TLAPS.

I asked the sender of the message to provide me the offending source module(s) off-list and will summarize the findings when I hear back.
