point, probably just the `.series()` method (without Puiseaux). I agree
that the code itself is cruft, just not the name :)

function. It would cause problems in the future if that ever changes. We
should also add some doctests to make sure it only returns Taylor
expansions.
Well, I would envision it would have a special keyword that would require
returning only Taylor series. Presumably `.series()` should also have
this, don't you think? Even if that weren't the default behavior.
> This can also be done as a part of #6119. Then, instead of a deprecation
message we give an error pointing to the `.series()` method.
Sounds good.
