Review Comment:
   In this 
[comment](https://github.com/apache/spark/pull/47146#discussion_r1670245557) I 
gave 2 examples when it can be `None`.  We can also add UUID there, but I don't 
think it makes sense to do it because surrounding loop will have label which is 
logically correct, and if user adds `BEGIN` and `END` block then the label will 
be appointed to that block automatically because it will pass through 
`visitBeginEndCompoundBlock(ctx: BeginEndCompoundBlockContext)`.
