What does the comment add to the assertion? Isn't it all obvious? Just
wondering; if you genuinely think it isn't, I'm not going to argue.
Except about the long line, which you could easily avoid:
assert isinstance(self.val, str) # comment value MUST be str
> if self.val.startswith('##'):
> # End of doc comment
> if self.val != '##':
