:-) I meant what I wrote: a comparison on the right producing a Boolean 
which is assigned to three variables in a list. The parentheses were to 
try to make it a bit clearer, and I note that a Perl list is in 
parentheses rather than brackets.

I'm not saying I like it, or that it's Pascal. But something like that 
would probably upset the fewest people that matter. Perhaps I should 
have said

[a, b, c] += Ord(d = e);
