However, this claim would imply that stringification defines a bijection between objects and their hash keys. Ergo, hash keys are all you need! ;-) in theory yes, practically no. There is no pure perl way to get the ref from the stringification, as long the relation is stored in a hash (sic). And yes collisions can happen, when strings and references are mixed into one set...then resulting into the need of a specialized stringification. Cheers Rolf
