Looks like you've done a good job so far, and have even put in a fair
amount of docs. Impressive! Just some minor thoughts:
* I think you should consider using ByteStrings instead of Strings in
a lot of places (eg, headers).
* In m2_parse, it looks to me like usage of Parsec is overkill, since
a simple break would work. As a plus, if you also switch to
ByteString, you could use breakByte which will give you a highly
optimized parsing function.
* For response_body, I'd **really** avoid usage of String. In fact,
some form of enumerator would be very good there. But at the very
least, please switch to a lazy ByteString.
I can't really say too much more without knowing more of the internals
of zeromq and mongrel2, but I think this is a good project to have
going for the Haskell community. Thank you.
Obviously I'm biased here, but I'd love to see a WAI wrapper for
mongrel2. Would you be interested in either having this package
provide a WAI interface, or writing a separate package that wraps this
package and provides one? I'd be happy to offer some help if you're
