> Is there a particular use case for arithmetic with PrimValues and tensors?
Primarily for cases where a dynamic computation requires use of a dynamic
shape (e.g. RMS_norm). Or simpler cases, like computing the mean.
```python
@R.function
def mean(A: R.Tensor(['m','n'], 'float32') -> R.Tensor(['m'], 'float32'):
n = T.int64()
sum = R.sum(A, axis=1, keep=False)
output = sum / n.astype('float32') # Allow expressing this step.
return output
```
