Not speaking for all Go programmers, but I think there is a lot of merit in the idea of "making zero a meaningful value". Zero Is Initialization (ZII) is a whole philosophy that uses this idea. Also, "nil-punning" in Clojure is worth looking at. Basically, if you make "zero" a valid state for all types (the number 0, an empty array, a null pointer) then you can avoid wrapping values in Option types and design your code for the case where a block of memory is initialized to zero or zeroed out.
