I'd say it is questonable if SequenceableCollections should be
comparable by default.

is (a b c) equal or lower than (b a c) ?
Doesn't this depend heavily on what is in the Collection and what the
meaning of the Sequence of two Collections is?

So I'd say there is not much use in putting comparisons into the base
class library, because there is a ton of assumptions about the
Collections in whatever implementation one can imagine. I would assume
that this is the job of some business object that holds objects in a
SequenceableCollection. Don't you think?

The fact that other languages provide such an implementation doesn't
mean much to me, to be honest. I choose a SequencableCollection in order
to keep objects in a certain order, nothing more, nothing less.

I think it is important to not get "overridden" by the fact that
something is extremely easy to do in Smalltalk. We can easily make bad
mistakes, just because we can.

Just my 2 cents
