Since the release, a couple people have sent in feature requests, so I'm going to put out 0.4.9 in a day or so. New features will be: - tryIO: runs an IO computation, and converts any exceptions into ``throwError`` calls (requested by Kazu Yamamoto) - checkContinue: encapsulates a common patte

[Haskell-cafe] object oriented technique

I've been trying to learn Haskell for a while now, and recently wanted to do something that's very common in the object oriented world, subtype polymorphism with a heterogeneous collection. It took me a while, but I found a solution that meets my needs. It's a combination of solutions that I saw on

[Haskell-cafe] HsOpenSSL package fails to install

Hi all, I tried `cabal install HsOpenSSL` and it died with some errors about 'i2d_of_void'. I'm on Mac OS X, gcc 4.2. The symbol 'i2d_of_void' is defined by a macro in the openssl/asn1.h header, which is indirectly included, so I don't see the problem. Any ideas? If this is a bug, is there a
