something i ran into when reading lut: http://lambda-the-ultimate.org/node/1641 http://lambda-the-ultimate.org/node/1453 http://www.ipl.t.u-tokyo.ac.jp/~tops/done_seminar06.html "In object-oriented languages, it is easy to extend data by defining new classes, but it is difficult to add new functions. In functional languages, the situation is reversed: adding new functions poses no problems, but extending data (adding new data constructors) requires modifying existing code. The problem of supporting both directions of extensibility is known as the expression problem." Looks like what i'm trying to accomplish is very much related to this. Some bones to chew on before diving into the theory: are binary operations enough? Unary operations are really just object methods. For what i need them, can i assume i can construct multi-ary operations from binary ones?
