in thread How to cut strings from the end

Could you explain how this works? I was trying these days to dismiss the first element of an anonymous list, then I got this code: 

(undef, @list) = split /\s+/, $str;

[download]
I was wondering if something like that could work, but it doesn't: 
@list = (split /\s+/, $str)[1..$#a];

[download]
Thanks in advance.

    His code assumes @a is empty, which means $#a returns -1, so he's doing (...)[-1 - 2 .. -1] which is just (...)[-3 .. -1]. Your case cannot be handled in a similar manner -- you'd need to know the size of the list being returned by split(). Your first approach is fine.
