Review comment:
@LielBach, I am very sorry for late responses. I have thought about this
and had some discussions offline with other people too. Can we, for now, switch
`Exception` to use built-in exception classes for now? For example, `Exception`
here could be just simply `RuntimeError`.
Throwing the plain `Exception` is the main reason I raised the JIRA in any
event.
