What confuses me, at this point, is this: I originally wrote the D code using foreach in this style:

foreach( i, ref parentString; strings )
    foreach( j, ref childString; strings[ i + 1 .. $ ] )

Essentially, the value of j printed to stdout should always be larger than the value of i.

j is counted from current begginning: from 0
strings[i+1..$][0] - its right behaviour
