Two unrelated features on top my wishlist would solve most of your issue as a byproduct:  
Replacing variadics ([[Discussion] Variadics as an Attribute](https://forums.swift.org/t/discussion-variadics-as-an-attribute/5186)) and constants as generic parameters ([Proposal: Compile-time parameters](https://forums.swift.org/t/proposal-compile-time-parameters/1250)).  
With those, your signature would be

```
func mean(_ alongAxes: @variadic MinimalSizeArray<Int, 1>) -> Tensor

```

I think it's better than adding yet another special case (even if it takes longer to be implemented).
