So the above are equivalent.
I think not, Andrew ... Martin is correct.
yep... I've kind of blogged about this a while back:
http://ajwelch.blogspot.com/2007/08/when-b-and-b-both-return-true.html
...but it still always catches me out.
The rule I mention there is "never use != where both sides are
sequences of more than one item" which is why I thought ". != x" would
be ok... but it looks like that should be:
"never use != where one side is a sequence of more than one item"
