Apologies for missing the meeting today -- I don't seem to have the
meetings properly entered into my calendar and due to the time difference,
I don't see Peter's reminders until after I start work.

I have a question about what someone wrote on the Wiki:

Can someone clarify (on the wiki) *when* it the normal precedence doesn't
hold. What surprised me when I first looked into notations and precedence
(20 years ago -- yikes!) was that although a symbols might have many
different meanings, the precedence relationships it has didn't seem to
change. I attributed that to people trying to avoid confusion when using
familiar notation for new functionality. Having '∨' have a different
precedence relative to '∧' in some cases seems very strange to me. But
mathematicians do strange things at times (especially logicians ;-).
