Comment:
Ok, with the dependencies #13125 and #14802 there remain two failing
doctests in `piecewise.py`:
{{{
File "src/sage/functions/piecewise.py", line 493, in
sage.functions.piecewise.PiecewiseFunction.EvaluationMethods.extension
Failed example:
g(3)
...
File "<doctest
sage.functions.piecewise.PiecewiseFunction.EvaluationMethods.extension[3]>",
line 1, in <module>
g(Integer(3))
File "/home/ralf/sage/local/lib/python2.7/site-
packages/sage/symbolic/function_factory.py", line 387, in new_f
return f(ex, *new_args, **kwds)
File "/home/ralf/sage/local/lib/python2.7/site-
packages/sage/functions/piecewise.py", line 398, in __call__
return self.subs(substitution)
File "expression.pyx", line 4212, in
sage.symbolic.expression.Expression.substitute
(sage/symbolic/expression.cpp:20863)
File "/home/ralf/sage/local/lib/python2.7/site-
packages/sage/functions/piecewise.py", line 209, in _subs_
raise ValueError('point is not in the domain')
ValueError: point is not in the domain
}}}
and the same in line `498`, as well as more than 200 failing doctests in
`piecewise-old.py` because of the deprecation.
