A lot of other built-in operators are missing. I'd like to add opGcd() 
(greatest common denominator), opFactorial (memoizing O(1) 
implementation, for advertising the terseness of D on reddit), opStar 
(has been discussed before), opSwap, opFold, opMap, and opFish (><>) to 
your list. Operations for paraconsistent logic would be nice, too. After 
all, these are operations I use quite often ==> everyone must need them 
badly.

Sounds perfect.
