I took the meaning as: Array processing can cause hidden bugs (like GOTO). The bugs are usually introduced when the size of the array changes while processing.

Also ‘find’ing and ‘filter’ing arrays is more error prone (like not properly handling a miss on a find).

I don’t completely agree with the author, but the idea that more care needs taken when dealing with arrays is worth considering.

Arrays will always have important uses. Tuples, enumerations, and the like. However, ‘n’ database records shoved into an array and then iterated over in a for-loop is a cumbersome way to structure a program.

That’s my take on it.
