in thread I need help with some recursion

So don't apply it to all the lines. This seems to produce something close to your desired output:

my %seen; for (my $i = 1; $i < @lines; $i++) { next if $seen{$i}; my @results = line_closure($i); print Dumper \@results; $seen{$_}++ for @results; }
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
