I goofed and misread what `mlir/test/mlir-tblgen/op-python-bindings.td` is - it is not the test that actually generates python bindings that can be used in tests. That's [mlir/test/python/python_test_ops.td](https://github.com/llvm/llvm-project/blob/9315645834ea81cf9550364a4950f289e9706a26/mlir/test/python/python_test_ops.td).

What I'm proposing is you just copy-paste 

```
def SameVariadicResultSizeOp : TestOp<"same_variadic_result",
                                      [SameVariadicResultSize]> {
  let results = (outs Variadic<AnyType>:$variadic1, AnyType:$non_variadic,
                 Variadic<AnyType>:$variadic2);
}
```

into `mlir/test/python/python_test_ops.td` and then create/query it in `python_test.py`.
