I found this whole discussion irritating because not a single person mentioned that with the memory demands of a web browser that you might not want GC. You can say all this BS about momentum but in my mind avoiding GC is probably the best and most relevant reason in 2013. Thank you for mentioning it.

Shows how dependent on GC a large part of the community of developers have become - they are incapable of imagining a world without it.

(PS: I am amused when people mention that being 20-50% slower is described as fixing the performance gap.)
