A remark on the proposed syntax:<br> onChange == [name1, name2, name3]<br>defines a set of slots by explicit enumeration, whereas<br> onchange == [ ! name1, !name2, *]<br>defines a set my subtracting the enumerated slots from the full set.<br>
<br>I think that using<br> onChange == [ ! name1, *, name2 ]<br>doesn't make sense, since "name2" is already in '*'. This means that<br>only negated slot names make sense in combination with '*'. This,<br>
in turn, means that '*' in addition to a list of negated slots is<br>redundant.<br><br>Therefore, only a list of all positive <i>or </i>all negated slot names makes<br>sense. Thus, all possible sets can be defined by permitting nothing<br>
but one of these forms:<br> onChange == [<name>,...]<br> onChange == [*]<br> onChange != [<name>,...] // subtract all enumerated from full set<br><br>One can also permit these two identical forms:<br> onChange == []<br>
onChange != [*]<br>and<br> onChange != []<br>which is the same as<br> onChange == [*]<br><br>Best<br>-W<br><br><br><br><br><div class="gmail_quote">On 31 July 2010 20:53, Mark Proctor <span dir="ltr"><<a href="mailto:mproctor@codehaus.org">mproctor@codehaus.org</a>></span> wrote:<br>
