Thats more or less the fall-back I considered. As long as you don't have more than 2^53 objects that should probably be fine - can't imagine that being an issue any time soon (or ever).

Start at -2^53 and you get twice as many objects. Everything beyond that is probably too much work to be worth it.

Just want to say that I would like to have a BigInt implementation in the sys pod; that would be nice, and there are implementations in JS afaik. (see http://shootout.alioth.debian.org/)

Yeah I think that should be fine - especially given the finite lifetime of browser pages.

Not sure we'll see that in sys - but would pretty straightforward to provide that in your own pod - could see a lot of stuff like that in a math pod.

Why are you guys concerned about this so much?

About hash support? Its pretty core to equality and an efficient Map implementation.

I made an small implementation to make the obj.hash function to work in JS
hashCounter = 1; fan.sys.ObjUtil.hash = function(obj) { if(obj.m_hash === undefined) { obj.m_hash = hashCounter++; } return obj.m_hash; }andy Wed 26 Oct 2011
