I believe it works like this:- `$gene->display_id # Invoke the display_id # method of $gene object [ ] # construct anonymous array # around returned value(s) @{ } # dereference same " " # Interpolate into double- # quoted string` [download] although I'm sure others will correct me if I've got it wrong!

If i'm not mistaken, the explanation given on the Perl idioms explained page is the same as the explanation i offered in my previous comment which I quite here `are you creating a reference to this variable $gene->display_id and th +en deferencing it straight away with ${ }` [download] I'm double checking as I'm not very confident with perl	[reply] [d/l]
