The loop would be better written:

for my $sub (@{$Document->find('PPI::Statement::Sub') || []}) { next if $sub->forward; for my $child ($sub->children) { if (ref $child eq "PPI::Structure::Block") { $child->start->add_content("my mars code"); } } }

The next if ... saves a level of indentation and is easier to understand (at least for me) than an unless.

Using a Perl style for loop in place of the C style for loop is easier to read, easier to understand, more compact and much less likely to get wrong.

True laziness is hard work
