I need for this task one clock.
I can do a clock (in binary values) with true and false
or 1 and 0 or so with a variable.
I can do this with loops or functions that inverts their
last value (true -> false   and false -> true) with simple
toggling.
I then could use this value and do things depending on the value.

But this one clock I also can do with two mutual recursive
functions. Each one represents the work that must be done
in one state (or more precise: when switching from one state to the
other).
So with two functions that call each other recursively I can
do a toggling value (state machine with two states) by
func_x1 calling func_x2 and then func_x2 calling func_x1.

Another reason why I started intuitively with a recursive
definition of my code here.
