There is also [TaylorSeries.jl](https://github.com/JuliaDiff/TaylorSeries.jl), which [could perhaps compose with Symbolics.jl](https://github.com/JuliaDiff/TaylorSeries.jl/issues/340).

I have made quite a hefty rewrite of the perturbation example. My goal has been to significantly shorten it and better display the features of Symbolics.jl, and particularly the power...

I would appreciate it if someone looks at this :) Suggestions are welcome! Particularly regarding how you think the public Taylor series interface should work, i.e. the current `series`, `taylor`...

Thanks for the feedback, I agree with many of your points. Maybe splitting the changes according to your 3 incremental stages would be the best approach. > What does Symbolics...

Alright I will try to do it in the near future.

I rebased and incorporated some of @karlwessel's suggestions. Hopefully this reaches a balance point. I'm not 100% convinced the current `series()`, `taylor()`, `taylor_coeff()`, `...` interface is optimal, but hopefully it...

[noblock] Thank you very much. I also much prefer just CLASS, and reverted back to it now. Let me know if there is anything else I should do to complete...

[noblock] Is merging still blocked? Due to > Name does not meet all of the following: starts with an upper-case letter, ASCII alphanumerics only, **not all letters are upper-case**. Maybe...

[noblock] I need help with a manual merge here. CLASS.jl is a wrapper around [CLASS](http://class-code.net/), which is a popular C code in cosmology for solving the linearized Einstein-Boltzmann equations. CLASS...
