We will need to write one, yes.

Yes it would be nice to just make latex strings.

We'd need to think about this a bit. It is somewhat of an alias, but if someone does `a(tau)` should it error? Or would that just be nice syntax to...

Use a wildcard. ```julia julia> @variables t f(..) 2-element Vector{Any}: t f⋆ julia> expand_derivatives(Differential(t)(f(t^2))) 2t*Differential(t^2)(f(t^2)) ```

We should probably add it to https://docs.sciml.ai/Symbolics/stable/manual/variables/#Symbolics.@variables the docstring. > What does it mean? (Is it a macro thing?) It's a wildcard. It's a call variable, but with a lazy...

For that use case though, wouldn't you build function?

This is a limitation of ForwardDiff. I think if you switch it to a differentiation method in the nonlinear solve that is not ForwardDiff it should work fine. Let me...

> @ChrisRackauckas would creating a SciML rng interface that works across serial/parallelism modes make sense as a small grant project? Or is it too complicated to expect someone to tackle...

The purpose of TaylorDiff is that you wouldn't want to nest calls to TaylorDiff, you instead just use a higher order derivative. If you do the TaylorDiff derivative with Val(4)...

Those are definitely needed.
