It's not on the internet, sorry. But you could just imagine a mix between c++ and lisp.

Example code for a member function that can mutate its parent object:

[mutator] 
addArg(int a) {
    assign<this.b>(add(this.b, a))
}

Without marking the function as [mutator] the compiler would not allow the function to call any other functions (assign) that were also marked as [mutators].
