one more question on reference,
if say you have sub as below
my @arrayref;
sub do_something {
my $something = @_;
open FILE, "$something", or die;
while (<FILE>) {
my @array = map (split /,/)[1,2,3,5];
push @arrayref, [EMAIL PROTECTED];
}
close FILE;
}
my @arrayref_copy = do_something($something);
Let's for a moment forget about my inefficient style and just look at
the last step.
If I wanted to use @arrayref_copy and pass it into another
subroutine,should I reference them again?(if file itself was pretty big?)
another_sub([EMAIL PROTECTED]); <-- is this the right thing to do? or is
this redundant since array is already collection of reference?
sub another_sub {
}
