   > Yeah, the technical explanation for this is that this kernel is implemented as a unary kernel (so the only "argument" are the input strings), and the start/stop/step are passed through the SliceOptions class. And only actual arguments are automatically broadcasted (i.e. accepting scalar or array types as input).
   
   It there any plan for implement this vectorized kernel? It's a common in SQL scene, I can help with this if it's planed.
