Removal of these five lines isn't about replacing assert_no_error(),
it's burying dead code: err is initialized to null, and every place
where err can be set is followed by an assert_no_error(), therefore err
must still be null here. Correct?

You could use the opportunity and drop the space between cast and its
operand, for consistency with the other casts around here. No need to
respin just for that, of course.
