As with /lisp/ I tend to grab my own copies of papers I think I'll want to refer to later in case the original URL vanishes in a puff of bitrot :)

Heh, neat to see you've got the Perceus paper there too. That is in fact the other part (the "ARC") of Nim's memory management for those unaware - with the only differences being Nim frees memory at the end of scope, rather than last use, and and Perceus maybe might be atomic (do not fully remember. ARC isn't atomic.)
