View The Signs of Soundness
Hello scala, my old friend
I've come to take you home again
Because a feature slowly creeping
left me plagued with doubts and weeping
and the version that was tagged in the repo
just has to go
it lacks the signs of soundness
On sleepless nights I hacked alone
applying ant and other tools of stone

;; let's create a simple protocol that just returns a number
user> (defprotocol NumberP (number [_]))
NumberP
;; now we'll create an implementation that always returns '1'
user> (deftype One [] NumberP (number [_] 1))
user.One
;; unsurprisingly, this type only has a single static value, which wraps the '1'
