Husk is a prefix-based (similar to Pyth) golf language related to Haskell. The language is strongly typed. Most builtins have more than one independent overload of different type and different order (unlike Pyth, which requires operands to be entered in a specific order). The compiler uses heuristics to make the program well-typed: it chooses between overloads of builtins, and by inserting parenthesis and default values with certain restrictions. The language uses an 8-bit source character set unique to it. It is optimized for Code Golf SE golf rules, so there are no IO operations, only pure functions. However, a langauge without IO is untestable, therefore IO is taken via command-line arguments and is accessible via one of the superscript number instructions.
