If you're creating an array you should use parenthesis ().

Subject: it's probably just me
Hi perl mavens,
I'm sure I just don't understand something here, but this one makes zero sense
to me:
The following snippet prints a 1
local @aList;
push @aList, ['first','second','third'];
my $nCount = @aList;
print "count: $nCount";
BUT, if I add one seemingly irrelevant line ( the second one below ), something
crazy happens:
local @aList;
print "non-existent value: $aList[0][0]\n";
push @aList, ['first','second','third'];
my $nCount = @aList;
print "count: $nCount";
instead of printing a 1, the last line prints a 2
So the reference in the first print statement to $aList[0][0] appears to have
the affect of creating a row in the array.
Is this supposed to work this way? Why would such a reference to a non-existent
array row result in the creation of an array row?
Thank you.
