Yes. (Even ignoring the oh-so-tempting complex number joke ;-)). As
has been seen here there's no agreement on the "right" choice of which
root of -1 to choose. Or possibly more accurately, no-one else is
agreeing with your suggestion that we choose a different option for
the case you're arguing over.
And to be 100% precise, you asked for the results of three *very
specific* calculations to change. I guess you actually want something
more general - or are you really OK with (for example)
Fraction(-1,1)**Fraction(2,3) changing as you request, but
Fraction(-2,1)**Fraction(2,3) remaining as it currently is? You still
haven't clarified (no-one has particularly asked yet - you may
consider this a request to do so if you like) how you propose in
general that the result of
Fraction(-1,1) ** Fraction(a, b)
and/or
Fraction(1,1) ** Fraction(a, b)
or maybe even more generally
Fraction(c,d) ** Fraction(a,b)
would change. What exactly are the special cases you want to define
different results for? What is the process for choosing the result?

And that part of your proposal has not generated much controversy.
Maybe if you proposed only that, you might get that change made? I
haven't considered the ramifications of that because the discussions
about -1 are obscuring it, but it might be relatively uncontroversial.
