afaik, your code anyway will not work on non-x86 architectures, because your `storable` definition use unaligned reads which are not supported outside x86 world
I don't think I understand what you are talking about. Are you referring to the code that you quoted or some other code? I'm on PowerPC / Mac OSX and the code above works for me.
and about ":+:" - read "Derivable type classes [http://research.microsoft.com/~simonpj/Papers/derive.ps.gz]" and "7.11. Generic classes" of ghc manual
I'll take a look, thanks! My question was _not_ what :+: was but how to pass a "list" of, say, a :+: b to my constructor Foo Int String (assuming types match) such that a is taken as the Int argument and b as the String one. Thanks, Joel -- http://wagerlabs.com/
