valueDiff for arrays?

[Mark Waddingham]

Alex Tweedly didn't talk nonsense... Byte x [to y] of z is (truly) constant time if z is strictly a binary string.

tArray[x] is constant time if x is already a name - otherwise the string needs turned into a name.

If x is coming from repeat for each key x - then it will already be a name.

(Not sure if that helps!)
