Yes but unless you have a very strange definition of "2 sequences are
different" don't use != on that day.
!= is true if _any_ element of a is not equal to any element of b so it
is only false if all items of both sequences are equal to the same value.
ah of course... took a while for the penny to drop there.. you are
right, this really does fall into the 'you never want to use it'
category.
