That's interesting Bas. What bothers me about ByteStrings is that they need
to be "pinned" inside the heap,
preventing the GC from collecting them. This is more than an issue, I
think, if a program uses them massively
and they needs to be allocated persistently (example: a long-life
constant). I know is still a marginal case, but
knowing that a part of my heap is pinned makes my sleep quality degrade :(
I assume that working with vector remove the problem, correct?
