I'm wondering about the record usage where a record would have relations
between its fields. This would be best explained with the following example:
user=> (defrecord Time [minutes seconds])
user.Time
user=> (->Time 0 59)
#user.Time{:minutes 0, :seconds 59}
user=> (update (->Time 0 59) :seconds inc)
#user.Time{:minutes 0, :seconds 60}
It's not very nice since 60 seconds is not really a valid value. If it
would be possible to define so that
user=> (Time. 0 60)
#user.Time{:minutes 1, :seconds 0}
then if I'm reading emit-defrecord correctly, assoc and therefore update
etc. would work as expected here. Would this be semantically against
principles of record or could some kind of structure to modify the fields
while creating a new instance of a record be considered as part of Clojure?
