Recall that 0 .. $#array; gives you a list of all the values between 0 and the maximum index of @array, or, in other words, the list of the indexes of @array.

That bit of code assumes (and I made this assumption explicit) that the members of @names map 1:1 onto members of @desc; and if that is true, then 

0.. $#names

[download]
and 
0 .. $#desc

[download]

yield up the same list, so either is acceptable.

HTH!
