I think this idea is great! Down the line we may move this out to a separate SciML/PlanarMechanics to reduce the loading time of the standard library, but we can...

Alright cool, sounds like a good plan. Let me know if you need anything. Our devdocs should be helpful if you want to get it into OrdinaryDiffEq.jl quickly: http://devdocs.juliadiffeq.org/latest/

First step here is to make an MWE. It doesn't look like SciMLSensitivity is related, so see if you can recreate it with differentiating: ```julia interpolator = config.interpolator_type( alpha_values, config.t_data,...

Does this require runtime activity? In the solver it's not setting that.

Interesting maybe @wsmoses can give a pointer to help out.

Yeah in the macro it should just `ModelingToolkit. ...` > But in general you cannot even assume that ModelingToolkit is defined in the calling module... It can just be a...

`reduce(hcat, u)` is a fairly expensive operation.

Doing it once for construction is fine. But note that only works for the linear algebra. If you do that, you will change the type of the output, so something...

Does such a jll exist now?
