Ah nevermind, a function and a const global variable can share the same name.

In addition, we can write simplification rules to optimize ```julia @inbounds for i in 2:length(a) out[i] = a[i] end ``` away when `out === a`. I made a mistake in...

Do you mind to check a few other functions and make a PR?

Differentiating wrt `x + y` is not supported.

This is slightly different from the metadata system that we have currently. We don't propagate the metadata for now. Propagating metadata requires a bit of work. For instance, we need...

That's not related to this issue. Could you open another issue?

That true is not related to this at all.

We need to clarify what is "compilation" time. I think @LiborKudela is talking about Julia compilation time for the RHS and the Jacobian of the DAE definition. @visr is talking...
