So, the patch is: "just revert this change".
Or... use your own UIO instance. That's why it's a type class!
Why should I rewrite the UIO instance, if one already exists?
Anyway, for the background on this:
Tue Nov 18 08:44:46 PST 2008 Malcolm Wallace * Use hFileSize to determine arraysize, rather than encoding it in the file.
"Here is a patch to the uvector library that fixes hGetBU and hPutBU to use the filesize to determine arraysize, rather than encoding it within the file. I guess the disadvantages are that now only one array can live in a file, and the given Handle must indeed be a file, not a socket Handle. But the advantage is that one can read packed raw datafiles obtained externally."
Still, again, I'd point out that uvector is alpha, APIs can and will change.
Ok, with API changes. But they *should not* break normal package usage. That patch simply introduced a bug in uvector. If you think that the patch is useful, then the patch should also include a modification to the UIO instance for a:*:b. Regards Manlio
