an exploration of the memory implications of call-site caching for protocols

	;; 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'

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
