 Review comment:
   I don't think a new status code is needed. Can you return `Invalid` instead? 
As a matter of style, we should try not to use Status for routine error 
handling in C++. I think having this bubble up as an exception in Python is OK 
for now, but if we need to do zero-copy detection in C++, we are going to want 
to handle that in a different way.
