   This is a bit surprising but also expected. The memory for the variable width strings is allocated in one block so writing different content in that memory with `set` will not work correctly. In general, Arrow data structures are optimized for reading and if you need to make changes, you are better off making a new data structure. Supporting write here would mean we need to move all the memory for the strings in the vector around. 
   
   If you only have a limited number of strings, you can use a dictionary and then re-assigning a value should work. 
   
   Closing as working as expected for now.
