Functional Unparsing

    A string-formatting function such as printf in C seemingly requires dependent types, because its control string determines the rest of its arguments.

    We show how changing the representation of the control string makes it possible to program printf in ML (which does not allow dependent types). The result is well typed and perceptibly more efficient than the corresponding library functions in Standard ML of New Jersey and in Caml.
