You can do following http://dpaste.dzfl.pl/41c57f89a5a0
The reason of compile error is your using a range as a separator, change 
it to single symbol and it works. Also I used 'array' after 'take' to 
make range bidirectional to let next 'retro' works. And 'join' joins 
result to string with '.' as a separator.
