Check generic signatures #163
I've examined the generics on the temporal classes twice now. It isn't possible to enhance their generics without making a terrible mess. Because Java doesn't have the Self-type generic, or the notional of parameter self-type generic where the class is final, and because LocalDate extends ChronoLocalDate, it is more or less impossible to go further than we have. This is unfortunate, but there you go.
The call remains open to check
