Description

Imagine I have

$$\dot{x}= f(x,g(x))$$

I want the diffeqsolve to return both the state and $g(x)$ at the different time points. I know from #62 that the DAE are not yet implemented, but is there a work-around that I can implement to output $g(x)$ together with the state?

Research direction

Start by reviewing the existing diffeqsolve interface and the DAE limitation referenced in #62. Determine whether the requested state and g(x) outputs can be supported without DAE implementation; the issue does not define a concrete workaround or completion criteria.
