Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/63612 This makes Tensor inherit from a new class TensorBase, that provides a subset of Tensor that doesn't directly depend on native_functions.yaml. Code that only includes TensorBase.h with thus not need to be rebuilt every time someone changes an operator signature. Making `Tensor` inherit from this class means that `const TensorBase&` parameters will be callable with an ordinary `Tensor`. I've also made `Tensor` constructible and assignable from `TensorBase` to minimize friction in code mixing the two types. To help enforce that `Tensor.h` and `Functions.h` aren't accidentally included, I've added an error into `Operators.h` if `TORCH_ASSERT_NO_OPERATORS` is defined. We can either set this in the build system for certain folders, or just define it at the top of any file. I've also included an example of manually special-casing the commonly used `contiguous` operator. The inline function's slow path defers to `TensorBase::__dispatch_contiguous` which is defined in `Tensor.cpp`. I've made it so `OptionalTensorRef` is constructible from `TensorBase`, so I can materialize a `Tensor` for use in dispatch without actually increasing its refcount.
