I don’t believe there is anything in CL that would prevent it from having a 
good concurrent, parallel garbage collector. One argument I’m hearing in favor 
of Go is that it has value semantics by default, which suggests that most 
objects are stored on the stack, but on the other hand, we have dynamic-extent 
declarations. Some of the detailed trade-offs might be somewhat different, but 
I don’t think there are any serious showstoppers.

But I’m not even remotely a GC expert, so I’m just guessing here.
