in thread array or array ref as variable

In my opinion, something like this could work ( dropping the sub, in case you don't need that sub for something else):

my (@fw, @vrf, @vlan, @portchannel);
my @arr_methods = ([ \@fw, &NT::FW], [\@vrf, &NT::VRF], [\@vlan, &NT::
+VLAN], [ \@portchannel, &NT::PORTCHANNEL] );

  foreach (@arr_methods) {
    @{$_->[0]} = ($_->[1])->extract($content, %CFG);
  }

I haven't tested it, the right hand-side of the assignment may not work, (but it's close), if it doesn't work, maybe one of the higher gurus here can fix it.

Run it and tell us the result

  my @arr_methods = ([ \@fw, \&NT::FW, 'FW'], [\@vrf, \&NT::VRF, 'VRF'
+], [\@vlan, \&NT::VLAN, 'VLAN'], [ \@portchannel, \&NT::PORTCHANNEL, 
+'PORTCHANNEL'] );
    foreach (@arr_methods) {
        @{$_->[0]} = ($_->[1])->extract( &slurpFile($CFG{$CFG{$_->[2]}
+} ), %CFG);
    }

If I run [ \@fw, &NT::FW, 'FW'] I'll get this error message:

Undefined subroutine &NT::FW called at main4.pl line 32.

but when I do this: [ \@fw, \&NT::FW, 'FW'] that error message is gone.

and when I run it I get this error message:

Can't call method "extract" on unblessed reference at main4.pl line 48.
