Hello Raul;

I don't see how you say Y is a function of X,Y. Is it: once you know x in X, and y in Y, you know y?

Do you have a more detailed version of that statement? I can
see how ?(arg,seed) is a function but I can't, in general,
see how foo(arg,range) would be a function, short of making
the range argument a function of the argument:

foo(arg,bar(arg))

which presupposes bar, which I don't see as a given.

Consider the relationship x,y where x is 0 or 1 and y is
0 or 1.

Then, y is not a function of x, but y is a function of x and y.

Consider the relationship X,Y where x is any real number and
y is any real number.  Then, Y is a function of X,Y, even though
Y is not a function of X.

Etc.

Note that there is no need to have a function bar(x) for this
condition to hold.

If this still does not make sense to you, I challenge you to
come up with an example relationship which cannot be made into
a function using this approach -- I'll describe the trivial
function for you.
