Zero one infinity rule

Zero One Infinity denotes literally a rule in programming of computer programs.

"Allow none of foo, one of foo, or any number of foo. "

"Allow not matter, it enables one or enable it in an unlimited number. "

For example, a computer algebra system should either be able to draw any graph, can draw a graph, or can draw many graphs as desired.

One thing to allow a single time, can be useful and is considered an exception. But as soon as one thing is two times allows, there is no reason not to allow even three times. And if it is three times allows, there will be someone who wants to see four times makes this thing. Any arbitrary limitation will be so rejected by the users of the computer program, which is why such restrictions should be avoided.
