* ensuring that offset_of!(Self, ...) works iff inside an impl block * ensuring that the output type is usize and doesn't coerce. this can be changed in the future, but if it is done, it should be a conscious descision * improving the privacy checking test * ensuring that generics don't let you escape the unsized check
