From: Eric Mahurin Date: 2005-10-09T08:17:10+09:00 Subject: using lambda/Proc can prevent a lot of garbage collection Does anybody else think it is a serious issue that a Proc holds references to all variables (including self) where it was created (through a block)? These references are held through Proc#binding. Although this does add some useful capability on occasion, this causes excess memory to be used (worst case could be a leaky program). Is this worth it? Personally, I think not. I'd propose that Proc#binding return something that only have access to variables referenced in the Proc. Even the self from the defining context would be prohibited if not referenced (possibly implicitly) in the Proc. Another option would be to make these references weak so that they won't prevent GC and those references would disappear if the referenced object (including the variables/variable-table) is GCed.
