Thank you.

I added this to the wiki so it can be easily referred to in the future instead of disappearing into the bowels of the forum: http://wiki.dlang.org/Language_design_discussions#Automatic_Reference_Counting_.28ARC.29_as_an_alternative_to_D.27s_Garbage_Collector

Everyone is welcome to help edit/summarize.
