Another case where I've used this: I had a loop using pointer arithmetic to iterate over argv (named v for brevity), and I only needed the second character of each argv string. The original code used v[0][2] for this (the pointer arithmetic moved v so v[0] was always the current string). Indexing being higher precedence than dereferencing meant *v[2] wasn't an option (it would be (*v)[2], which saves nothing), but 2[*v] worked perfectly and saved two characters while behaving identically to v[0][2].
