If you actually did have use strict in the included file patterns.pl, you'd have gotten

This is because do does not see lexicals in the enclosing scope, i.e. your my @LOGE, which I suppose was the idea. Rather, the @LOGE in patterns.pl is treated as a separate package variable.

You could use string eval instead (which does see lexicals in the enclosing scope). I.e., read the contents of patterns.pl into a string and eval it

my $config;
{
    local $/ = undef;
    open my $fh, "<", $MATCH_FILE or die $!;
    $config = <$fh>;
}
my $return;
unless ($return = eval $config) {

Alternatively (and usually better), create a proper module and use Exporter.
