Alright sorry, that was me being confused. I thought
address@hidden:n:1} was giving the (n+1)th element of the array
while it's not, it's giving the first element whose index if
greater or equal to n.

I thought

$ bash -c 'a[1664]=x a[51]=4 a[42]=1; echo "address@hidden:1:1}"'

would give "4" because in the sorted list of indexes (42, 51,
1664), 51 is the second.

While it gives "1" because "42" is the first element after "1".

Sorry for the bother,
