functions
These are just like procedures, but they return a value, and can be used
in an expression, e.g.
        function max(atom a, atom b)
            if a >= b then
                return a
            else
                return b
            end if
        end function
Any Euphoria object can be returned. You can, in effect, have multiple
return values, by returning a sequence of objects. e.g.
        return {x_pos, y_pos}
We will use the general term "subroutine", or simply "routine" when a
remark is applicable to both procedures and functions.
