one can use following construct declaring event: public class myclass { public event eventhandler<eventargs> someevent = (s,e) => {}; public void somemethod () { // interesting... ;) someevent (this, new eventargs); } } that allows raising event without need check if event null. now, let's object holds reference object of myclass, registers event , unregisters later on. var myclass = new myclass(); myclass.someevent += myhandler; ... myclass.someevent -= myhandler; myclass = null; will gc collect myclass if there no-op lambda expression still on event? i guess because object root no longer reference other objects... can confirm or prove otherwise? with code in question gc collect myclass if don't unsubscribe. relation other way around. myclass's event holds reference subscriber theoretically should worried subscriber not being collected. if unsubscribe subscriber collected.

i'm curious if there important libraries support python 3, since appears many libraries support it, happen support python 2. no, there no such index, create 1 classifier data on pypi. you make list of packages has "programming language :: python :: 3" or programming language :: python :: 3.0" or "programming language :: python 3.1", none of python 2 classifiers. http://pypi.python.org/pypi?:action=browse&c=214 possibly xml interface can useful: http://wiki.python.org/moin/pypixmlrpc

say want change value objects in array. range syntax lot more named loops. so tried: type account struct { balance int } type accountlist []account var accounts accountlist ... .... // init balances _,a := range( accounts ) { a.balance = 100 } that did not work since copy of entries accountlist , updating copy only. this work need to: for := range( accounts ) { accounts[a].balance = 100 } but code has lookup inside loop. is there way iterator gets references structs in accountlist? just let accountlist []*account. you'll pointers each account inside range.
