Comment:
I'm not totally sure of how this should be done as I don't know the
details of coercions, neither the details of the polynomial templating
used.
At least, my patch doesn't break any doctest for me.
It touch for methods, the ones using _coerce_.
It test for parent equality before applying coercion. I also introduce a
variable
`parent = (<Polynomial_template>self)._parent`
for readability.
