strings -- with an optimized path, rather than an TypeError.
I understand the lesson

Row(Any) class something like
class
I didn't even realize f'{n for n in row}' was already valid syntax. Since
generator expressions can usually only appear within parentheses, I assumed the
syntax wouldn't conflict with anything because you would need to parenthesize
the generator to make it work. Anyway, now I see that the better
