That how I was taught to round in school, so it doesn't seem at all
unusual to me.

Round-to-even means x.5 gets rounded to x if x is even and x+1 if x is
odd. This is sometimes known as banker's rounding.
OK. That's slightly
Dear list members,
In February this year there was a posting Why does sleep not work?
(http://www.haskell.org/pipermail/haskell-cafe/2009-February/055400.html).
The problem was apparently caused by signal handler interruptions. I
noticed the same (not with sleep though) when doing some FFI work

This sounds great! I really like using yaml for web development.
However, my last use case was for a non-techie, so I created a little
desktop application for editing the yamlbase, if you excuse the
neologism.
I think it worked quite well, because the user was then presented with a

Hi
Some good reasons for having a separate interface are: they can be
human-readable and human-writable (ghc's do not fulfill this criterion);
they can be used to bootstrap mutually recursive modules in the absence of
any object files (ghc uses .hs-boot files instead); other tools can
In a lot of cases though annotating all the recursive aspects with newtypes
is a _royal_ pain, and is even worse if you want the datatypes to be
instances of common type classes like Functor, Applicative, etc... (try it
sometime)
I don't advocate allowing infinite types wholesale, just in specific

There are a number of ways to fix this of various complexity, depending on
how many kinds of statements you have in your language and how adverse you
are to code duplication.
One option is to remove the recursion from your statement type and to make a
'base functor' like you've proposed with your
