{{{
sage: R.<y> = ZZ[]
sage: y.diff()

...
AttributeError:
'sage.rings.polynomial.polynomial_integer_dense_flint.Polynomial_integer\
_dense_flint' object has no attribute 'diff'
}}}
does not work. Neither does {{{y.differentiate()}}}. You can only do the
desired operation with
{{{
sage: y.derivative()
1
}}}
In the symbolic ring all of the above is allowed:
{{{
sage: var('z')
z
sage: z.diff()
1
sage: z.differentiate()
1
sage: z.derivative()
1
}}}
For consistency aliases {{{.diff()}}} and {{{.differentiate()}}} should be
added to all polynomial rings.
