Comment (by rws):
Replying to [comment:19 kcrisman]:
> It looks like there is still no proper deprecation for the "old"
piecewise stuff. Given that there seems to be a significant amount of
stuff that that has (even if in an antiquated form that should be redone),
perhaps a potential solution would be to do a deprecation of `Piecewise`
that leads to the old version, but where `piecewise` is the new one?
(Wait, I already said this in comment:11.)
Seems that Volker already implemented it, just the doctests have to be
adapted, and the `cmp` stuff from #16397:
{{{
sage: R.<x> = PolynomialRing(QQ, 'x')
sage: f = Piecewise([[(0,1),1*x^0]])
/home/ralf/sage/src/bin/sage-ipython:1: DeprecationWarning: use lower-case
piecewise instead
See http://trac.sagemath.org/14801 for details.
#!/usr/bin/env python
----------------------------------------------------------------------
sage -t --long src/sage/functions/piecewise.py # 3 doctests failed
sage -t --long src/sage/functions/piecewise-old.py # 203 doctests failed
}}}
I think I'll put some work into it to reduce doctest failures a bit.
