I have code that uses the following:

1. myArray = [0:["t", "o", "m"], 1:["s", "m", "i", "th"]];
However, I've found out that I never need an assoc array and a
"linear" array would be just fine, as in
2. myArray = [["t", "o", "m"], ["s", "m", "i", "th"]];
Is there any huge difference as regards performance and memory
footprint between the two? Or is 2. basically 1. under the hood?
If you don't need the features of associative arrays, don't use
them.
Normal arrays are much simpler, faster and (due to some
outstanding problems with associative arrays in D) less
bug-prone. Associative arrays, by definition, require a lot more
work behind the scenes for both reading and writing.
