GC

[piotrekg2 via Digitalmars-d-learn]

I would like to learn more about GC in D. For example can anyone 
explain why do we need memset(0) here: 
https://github.com/dlang/phobos/blob/master/std/container/array.d#L356 , doesn't it assume a certain type of GC? What if there is a need to change the GC algorithm in the future?

It would be great if you could point me out to articles on this 
subject.
