What's the practical difference between a (lazy) list of strict bytestrings and a lazy bytestring?
Lazy ByteStrings are head-strict. I don't know whether that's relevant here, though.
Or rather, element-strict. But I don't think that matters here, since writing requires element strictness anyways.
It may be significant if I write new versions to use writev for lists/lazys instead of calling write repeatedly, since we'd have to force all elements before calling into C. But then writev would require forcing the spine anyways (to get the length in chunks) so it wouldn't affect asymptotic behavior or memory retention.
Where "it" in the last sentence means "forcing all the elements". -- Live well, ~wren
