I guess I was not clear. I was only teasing you about nomenclature. The
question was not why you want self-contained recursive functions, but
why you have to call them "self-contained recursive functions", since
your definition of "recursive functions" already implied that they should
be self contained ;)

(Obliquely, I was trying to say that self-contained recursive functions
should be a proper subclass of recursive functions, not the same thing...)
