Hi Marek,
One problem with flip is the following.
Suppose that the value to be hold is controlled
under cond1, the flip is 1 under cond2 and 0 under
cond3. If between 2 and 3 the value changes 3 times
because you had 3 "true" cond1, which value will you hold?
On the other side, flip will give repetitive signals, Don may
ask to hold a value only once.
Think about, it is not that simple.
