Yes, and in both cases the language should provide tools so you don't have to deal directly with those edge cases. For example in Julia, for modular arithmetic with 1-based indexing there is mod1 [1], and for iterating in Julia you should use eachindex which will always work for both 0 or 1 indexed arrays.
