### functions with vector inputs

Are vector functions supported in sage?

as in:

```
f1(r,phi,theta) = 1/r
f2(r,phi,theta) = 1
f3(r,phi,theta) = 1
F = vector([f1, f2, f3])
```~~G=gradient(F) ~~G=rot(F) # vector function

An ancient post seems to suggest that ~~gradient ~~rot has to be defined with a positional python-argument like ~~gradient(*F).~~rot(*F).

Is there a way for ~~"gradient" ~~"rot" to take the vector symbolically as an argument?
