  • How do I define my own operators in the Io programming language?

I have an object: MyObject := Object clone do( lst := list() !! := method(n, lst at(n)) ) But when I call it, like this: x := MyObject clone do(lst appendSeq(list(1, 2, 3))) x !! 2 But I get an exception that argument 0 to at must not be nil.
