That's kinda bullshit, it depends on the GC implementation

D's GC is not good for 99.99% "of all software in the world", 
it's wrong to say this, and is misleading

Java's ones are, because they offer multiple implementations that 
you can configure and the, they cover a wide range of use cases

D's GC is not the panacea, it's nice to have, but it's not 
something to brag about, specially when it STILL stop the world 
during collection, and is STILL not scalable

Go did it right by focusing on low latency, and parallelism, we 
should copy their GC
