Subject: Re: [PATCH] Document arithmetic overflow semantics

    I think there is major confusion here between "undefined" in the 
    language-lawyer concept and "ambiguous" about what our internal nodes mean.

    Yes, we want to take advantage of the former.  But we need to try and 
    avoid the latter.

Strongly agreed.
