> The problem with automatic detection is that you only know the objective and some variables may be missing from there. If one unknown trajectory misses, then you by definition...

But, I suspect the function may fail if people throw more random objective functions at it. We need to be clear on what it can and can't do.

That may be a reasonable argument if we were at the beginning of SymPy's history (which, btw, seems to be before tau was proposed as the name of this angular...

Yes, that is a possibility.

Hi, thanks for preparing this. I have a few questions: 1. Is there a reason not to use the optimizations kwarg in cse for this (as I suggested in the...

To test the effects of slowdown you need something like `kane1 = models.n_link_pendulum_on_cart(20)` at least.

Sorry if I misstated. The slowdown I'm interested in is the timing of lambdify(). If we do pre and post substitutions, there is a slowdown associated with executing the lambdify...

Are you saying that your modification makes lambdify faster?

Ideally a fix would work with any types of SymPy objects where this may occur. `Derivative()` is one, but this may also occur with things like `Integral(f(t), t)` or even...
