I found that function mod2pi is not implemented yet, but mod works. Is there any list of implemented functions? Minimal working example is:

using Zygote

# This is working
gradient(x -> mod(x, 2pi), 1.)

# This is not
gradient(x -> mod2pi(x), 1.)

So that other people (like me) can help development of the interactive API. At the moment it is something alien that I Can just use through example. This is not the proper way forward...

(finally found Mouse in interaction/iodevices.jl...)

In Exercises 10.1, the outer product in Take the outer product of a vector v with itself and assign it to variable cross_v should be cross product.
