you are right, my conclusion was to simplistic. It doesn't matter if an array on the stack holds non ref data.
> I do not understand currently why the seq is no problem for the GC I don't know either, but I guess its because the GC has to check all the roots on the stack. For the seq it has only to check 1 root (the strings inside the seq are ref counted), for the array it has to check 16k roots.
