Why do references always trip me up? I tend not to use them greatly and always struggle when I do. Context: I was trying to make a subroutine return a reference to a slice of an array. I wrote\@array[0..3]
which just returned a reference to a scalar before finding what I needed was[@array[0..3]]
"An array slice is exactly the same as a list of individual array elements. Because you can't take a reference to a list, you can't take a reference to an array slice".

I knew the answer would be there - I just didn't have it with me at work today. It's one of those things where it looks so right (but just doesn't work the way you expect).Re:same problem

Now if you want some serious brain hurting, try this :perl -le '$x="abcdef";$y=\substr $x,2,2;$$y="gh";print $x'
(warning ! this behaviour is not documented ! use at your own risk !)
