Comment(by kcrisman):
Well, you can certainly implement Puiseux series. See #4618, where this
is already requested.
But having a command called "taylor" return things that are not Taylor
series is ... problematic. And I don't think that Maxima is recognizing
this necessarily.
{{{
>], ...)
`taylor (<expr>, <x>, <a>, <n>)' expands the expression <expr> in
a truncated Taylor or Laurent series in the variable <x> around
the point <a>, containing terms through `(<x> - <a>)^<n>'.
}}}
nothing about Puiseux, nor do any examples.
Now, our `.series()` is not named quite that way, so I suppose it's
possible we could have that. I still think it might be a little
confusing, so I would at the very least recommend that implementing P.
series be at #4618 and then adding a keyword or something (even default,
but maybe so that it could be disabled) here for the `.series()` method
would be what we would do here.
