Hi Sharan,
Yes it is the same but for readability reasons is better to use the @{}
solution. Think about a complex structure you could get something like
@%$variable which looks more like you are cursing cartoon style
then writing code certainly if the data structure gets a little more complex
then that.
So in nice looking code and for prosperity (you will not believe how long
some scripts can remain in use, they can quite often remain in use many
years after you stop working for a company) we should as smart perl coders
always use the cleaner looking and easier to read @{ %{ $variable } } } even
though the other way might save a few key strokes.
Regards,
Rob
