Well, I'm kinda late into this thread, but I have to ask:

Why would {0,1} be logically assumed to be true? I can't think of
any reason for it to be seen as such that's obviously superior
to all the reasons why it should be seen as false, or as invalid.

(Serious question there. If there's some reason I'm missing, I'd
be interested in hearing it, as the concept might have value in
several places.)

As of right now, I think having a sequence not be accepted as a
statement of truth or falsehood makes sense; that being the case,
a function like 'equal' becomes required to compare slices/strings.
With THAT being the case, a large portion of this thread becomes
moot, yes?
