Nothing is undefined in zkl (in theory). Numeric values like inf and NaN are "discouraged". "Void" is an object that is used as a "sentinel" for "I have no idea what the proper value should be" but it is just object that can be used like any other object.
<lang zkl>println(Void);
1+Void
if(Void){} else { 23 }</lang>
{{out}}
