I have no idea why you said one of the statements worked, because your entire snippet was full of errors, and I confirmed that by running on my machine with compilation errors.
Not sure whether my modified version is what you intended.
Begginer alert!!
I have just started learning perl and have got stuck. I need to initialize a hash array with values from a list. I've been told to do this using a split command, but its just not happening.
Here is the script and output:

Hi,
A piece of script from Perl-cookbook I do not understand, and post here for explanation.
The purpose is to find the element in either array (union), and in both array (intersection). Thank you in advance.
@a=qw(1 3 5 6 7 8);
@b=qw(2 3 5 7 9);

tie::hash::namedcapture
Tie::Hash::NamedCapture(3pm) Perl Programmers Reference Guide Tie::Hash::NamedCapture(3pm)NAME
Tie::Hash::NamedCapture - Named regexp capture buffers
SYNOPSIS
tie my %hash, "Tie::Hash::NamedCapture";
# %hash now behaves like %+
tie my %hash, "Tie::Hash::NamedCapture", all => 1;
# %hash now access buffers from regexp in $qr like %-
DESCRIPTION
This module is used to implement the special hashes "%+" and "%-", but it can be used to tie other variables as you choose.
When the "all" parameter is provided, then the tied hash elements will be array refs listing the contents of each capture buffer whose name
is the same as the associated hash key. If none of these buffers were involved in the match, the contents of that array ref will be as many
"undef" values as there are capture buffers with that name. In other words, the tied hash will behave as "%-".
When the "all" parameter is omitted or false, then the tied hash elements will be the contents of the leftmost defined buffer with the name
of the associated hash key. In other words, the tied hash will behave as "%+".
The keys of "%-"-like hashes correspond to all buffer names found in the regular expression; the keys of "%+"-like hashes list only the
names of buffers that have captured (and that are thus associated to defined values).
