New in this release is support for scatter/gather I/O (also known as

It depends on the underlying file control used by ghc. if it's the FILE

standard file descriptor (open instead of fopen), then it's limited by
ulimit.

Hello café,
I'm trying to write an executable that depends on Yogurt-0.3, readline

readline. Here is a small test case:

I'm still learning Haskell and also evaluating whether I want to use
the language in my work.
It seems like a fascinating language so far (although I don't know if
laziness will be a detriment later for me eventually), but I'm a bit
worried about the overall quality of its GHC implementation.
It has been slow for me today as well. I spammed up 3 released of a package
in rapid succession because it wasn't showing up in the list. Apparently
stuff is at least showing up several minutes after the upload completes
though as evidenced by the fact that I can see all of those versions now.

It seems there is a problem with tuples, too.
I have a:
[(Word16, UArr (Word32 :*:* Word8))]
This eats more memory than it should, since tuples are decoded lazily.
My bad, sorry.
I simply solved by using a strict consumer (foldl' instead of foldl).
