@array[2] is just an array with one element. ('a') ; and print prints out the element.

Subject: [Chicago-talk] Using "@" to reference element in array
Hi,
I just got a script at work where the writer used:
my @array = qw[adf af a adf asdfd];
print @array[2];
And it works!!
I thought that notation didn't go into effect until Perl6.
I've always done $array[2], and never tried the style above. Is there any reason not to adopt the style above in future Perl5 programming?
Thanks
Jay
