Yogurt is a free and small MUD client library developed in Haskell. Yogurt is a DSL embedded in Haskell. Unlike other MUD clients out there, Yogurt doesn\'t offer its own syntax; instead, it will rely on Haskell and naturally offers all Haskell\'s features. This means full control over what messages are sent, variables with any valid Haskell type, no ambiguity about whether a variable is expanded at hook define time or hook trigger time, no clumsy syntax, et cetera. On the other hand, this means you do not get the ability to change the installed hooks at runtime for free.
