Talk:Ephemeron

More detail needed
This article is quite a poor description of ephemerons; it misses out several important details. See http://docs.racket-lang.org/reference/ephemerons.html for a much more precise description (of the variant in Racket, but that variant has quite standard semantics). --David-Sarah Hopwood ⚥ (talk) 04:37, 5 January 2013 (UTC)

Also wrong
The set of keys and values for ephemerons that are to be collected are clearly not traced; the values are traced only if the key is reachable. -- Eddie Edwards
